Scattering and absorption of light by small particles - 百度学术

WebThe sunlight goes through the air, and when we look to one side of the sun—say at 90 ∘ to the beam—we see blue light; what we now have to calculate is how much light we see and why it is blue. Fig. 32–2. A beam of radiation falls on an atom and causes the charges (electrons) in the atom to move. WebThe scattered light can also be shown to be polarised using a filter of polarised light, just as the sky appears a deeper blue through polaroid sun glasses. This is most correctly called the Tyndall effect, but it is more commonly known to physicists as Rayleigh scattering—after Lord Rayleigh, who studied it in more detail a few years later. football player swallows tongue
