HELLO(:"" - posted by Isabel Maria at 8:23 PM i know i have posted twice but i've decided to post again :D and this is a MEGA huge post for me. *hears gasps* LOLLL. to make up for my lack of updates :DDD found this interesting thing on the net :P Why is the sky blue? The Earth's sky is blue because the air molecules (largely nitrogen and oxygen) are much smaller than the wavelength of light. When light encounters particles much smaller than its wavelength, light is scattered in all directions. This scattering is known as Rayleigh scattering. Blue light, however, is much more readily scattered than light of longer wavelength. In fact blue light is scattered some 16 times more strongly than red light. Consequently, the sky appears blue. Rayleigh scattering also provides the explanation for the colour of skies at dusk and dawn. A setting or rising Sun appears red because the blue light has been scattered away from the direct sunlight. Occasionally, other colours of the sky can be seen. These are caused by the scattering of light by particles much bigger than air molecules, sometimes larger than the wavelength of light. Dust particles, from natural or man-made pollution, can be many times larger than air molecules but still small enough to not fall out to the ground. If the dust particles are much larger than the wavelength of light, the scattered light will be neutral in colour, for example white or gray. By the same principle water molecules in clouds are sufficiently large to scatter all wavelengths equally. Therefore the scattered light contains all wavelengths and clouds appear white. If the dust particles are of approximately the same size as the wavelength of light, all sorts of interesting scattering phenomena may happen. This happens here on Earth from time to time, particularly in desert areas, where the sky may appear white, brown, or some other colour. LOLLL. interesting right? random. stumbled across this website :DDD shall do tag replies now. be honoured since i seldom do them. jk :P TAG REPLIES: DONE! ciao~ :) tmr if have time, will try to update 'bout the lunch and the church sermon :X Current song: "酸甜" by S.H.E and Fahrenheit :DDD (its currently playing on my playlist so including it :DD) peisze made me hooked onto S.H.E :DDD blame her haha :P currently reading And Then She Met the President's Son on fictionpress! :DD Labels: "酸甜" by S.H.E and Fahrenheit, And Then She Met the President's Son, FictionPress, three posts today :D |
