why is the sky blue? On a clear sunny day, the sky above us looks bright blue. In the evening, the sunset puts on a brilliant show of reds, pinks and oranges. Why is the sky blue? What makes the sunset red? To answer these questions, we must learn about light, and the Earth's atmosphere. THE ATMOSPHERE The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%). Argon gas and water (in the form of vapor, droplets and ice crystals) are the next most common things. There are also small amounts of other gases, plus many small solid particles, like dust, soot and ashes, pollen, and salt from the oceans. The composition of the atmosphere varies, depending on your location, the weather, and many other things. There may be more water in the air after a rainstorm, or near the ocean. Volcanoes can put large amounts of dust particles high into the atmosphere. Pollution can add different gases or dust and soot. The atmosphere is densest (thickest) at the bottom, near the Earth. It gradually thins out as you go higher and higher up. There is no sharp break between the atmosphere and space. LIGHT WAVES Light is a kind of energy that radiates, or travels, in waves. Many different kinds of energy travel in waves. For example, sound is a wave of vibrating air. Light is a wave of vibrating electric and magnetic fields. It is one small part of a larger range of vibrating electromagnetic fields. This range is called the electromagnetic spectrum. Electromagnetic waves travel through space at 299,792 km/sec (186,282 miles/sec). This is called the speed of light. The energy of the radiation depends on its wavelength and frequency. Wavelength is the distance between the tops (crests) of the waves. Frequency is the number of waves that pass by each second. The longer the wavelength of the light, the lower the frequency, and the less energy it contains. COLORS OF LIGHT Visible light is the part of the electromagnetic spectrum that our eyes can see. Light from the sun or a light bulb may look white, but it is actually a combination of many colors. We can see the different colors of the spectrum by splitting the light with a prism. The spectrum is also visible when you see a rainbow in the sky. The colors blend continuously into one another. At one end of the spectrum are the reds and oranges. These gradually shade into yellow, green, blue, indigo and violet. The colors have different wavelengths, frequencies, and energies. Violet has the shortest wavelength in the visible spectrum. That means it has the highest frequency and energy. Red has the longest wavelength, and lowest frequency and energy. LIGHT IN THE AIR Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits. Dust particles and water droplets are much larger than the wavelength of visible light. When light hits these large particles, it gets reflected, or bounced off, in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors. Gas molecules are smaller than the wavelength of visible light. If light bumps into them, it acts differently. When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates (releases, or gives off) the light in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the colors can be absorbed. But the higher frequencies (blues) are absorbed more often than the lower frequencies (reds). This process is called Rayleigh scattering. (It is named after Lord John Rayleigh, an English physicist, who first described it in the 1870's.) WHY IS THE SKY BLUE? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue. As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white. THE BLACK SKY AND WHITE SUN On Earth, the sun appears yellow. If you were out in space, or on the moon, the sun would look white. In space, there is no atmosphere to scatter the sun's light. On Earth, some of the shorter wavelength light (the blues and violets) are removed from the direct rays of the sun by scattering. The remaining colors together appear yellow. Also, out in space, the sky looks dark and black, instead of blue. This is because there is no atmosphere. There is no scattered light to reach your eyes. WHY IS THE SUNSET RED? As the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected and scattered. As less reaches you directly, the sun appears less bright. The color of the sun itself appears to change, first to orange and then to red. This is because even more of the short wavelength blues and greens are now scattered. Only the longer wavelengths are left in the direct beam that reaches your eyes. The sky around the setting sun may take on many colors. The most spectacular shows occur when the air contains many small particles of dust or water. These particles reflect light in all directions. Then, as some of the light heads towards you, different amounts of the shorter wavelength colors are scattered out. You see the longer wavelengths, and the sky appears red, pink or orange.

A man walks into a bar and sits down on a stool. Being the only two people in this rundown watering hole, the bartender walks over slowly to the man and asks him in a depressed tone, "What would you like?" The man replies back with nervous hesitation, "Do... you mind if I have a rum and coke?" Staring off into the empty wall of the bar, the bartender sighs then says, "Eh... Why not. Your service is better than watching these reruns of MASH on this broken television. I can barely understand where all this laughter's coming from when the punchlines are covered up with static. I feel that if I could take in on how the joke was being told that it could potentially fill that void I experience in day-to-day life, but in the financial state that I'm currently in, that huge hole that I sense in daily life will never ever be filled. Every morning I wake up and try to find a way that I could escape this feeling that I have at the bottom of my stomach. You know there was a time where butterflies flew around in my gut because this television worked just so damn well, but it seems that over time the butterflies ate one too many greasy cheeseburgers and drank one too many beers." While still concentrating on the empty space of the wall, the bartender starts to tear up. he wipes the tear away then continues on with his rant. "But that isn't the only problem that I have going on with me. Every night in my vacant and almost unfurnished apartment, I would prepare myself a TV dinner in the microwave and set up my recliner so I could stare out of my window and see what's going on in my neighbor's living room. Every night I would do this and watch him have his loud and raunchy drug-induced orgies with women and animals. They would light up candles and chant right in front of the beautiful orange glow before stripping off their clothes. I know that it's a great misfortune that even I myself know what is wrong with this picture that I just described to you, and yet simultaneously, it hasn't really dawned on me yet that what I've been doing is extremely creepy and intrusive. Even walking upon this shaky and seemingly everlasting tightrope of ambivalence, I can see what's the right answer but loneliness has a strong effect on a person. Upon its very appearance, it corrupts the personal ethics of some beings. Many times I've seen quiet men turn themselves into loud and mad animals to make themselves look like alpha males. Many times I've seen celibate women strip off their clothes and show flesh all for a pervert. Sometimes I just stay here at the bar and watch TMZ. I've even sense the loneliness when I looked in some of the eyes of the celebrities'. Their acts scream loneliness as they stumble around drunk and mumble words in front of some overpriced bar. Perhaps I'm just going nuts here. It's almost like I'm having too much fun when I take in at what I've become. I've fallen into the shape of a lonely bartender of an empty, empty place. This establishment used to be so full of life but now it's all shrunken up. I apologize, sir. I know I probably told you too much information, but I'm drunk and I felt that this is the only opportunity that I'll have before i relive that feeling again. It just won't stop. It goes on and on." After staring deeply into his drink for sometime, the man digs into the inner pocket of his coat to pull out his pack of cigarettes. The bartender murmurs out to himself as he reads the cigarette box, "Lucky Strikes, unfiltered." As the man pulls out a cigarette for him and the bartender, he says, "cheer up, man. we'll make the best of it." The bartender takes one and lights up with the man in the bar. After a few drinks, the man decides that he's going to wrap it up and hit the town. As the man is leaving, he lays down a hundred dollar bill and tells the bartender to take it. The bartender smiles and says, "thanks for listening to me, sir. you've been great." The man turns around and smiles then says, "No problem. Thank you for staring into my apartment."
