Scattering of light
Scattering Of Light
Normally, when you switch on a torch, you do not see a beam of light traveling from the torch. Similarly, during the day you do not see the path of the sunlight as it illuminates things around you. However, you can see the path of light if there is dust, smoke or other small particles in the air. You might have seen the path of sunlight streaming into a room through a gap in the curtains. You might have also seen it coming down through gaps in trees in the early morning mist. In both cases, the path of the light is visible from different positions.
You know that light travels in straight lines. So, for us to see the path of light from different positions, light must be redirected in different directions by the particles in its path. The phenomenon in which a part of the light incident on a particle is redirected in different directions is called scattering of light.
