Question and answer
what haooens to light when it changes speed
When light photons travel through air they lose speed by about 90 kilometers per second, but no energy is lost unless work is done (it's energy used in photosynthesis, etc.). Dust particles, etc., only scatter them. [ The only way in which light can change speed is by entering a different material with a different refractive index, or by exiting material into a vacuum. If the light enters the material at some angle other than straight into it, then it will be refracted. Refraction means that the light turns, this is the effect you can see when you have a straw in a glass of water. ]
