Question
What do you mean by reflection, refraction and absorption of light?
Solution
When light travelling through one medium, falls on the surface of another medium, the following three effects may occur at the surface of separation of the two media:
Reflection: A part of the incident light is bounced back into the first medium. This is called reflection of light.
Refraction: Another part of incident light is transmitted into the second medium and diverges or bends from its path at the surface of separation. This is called refraction of light.
Absorption: The remaining part of incident light is absorbed at the surface of separation. This is called absorption of light.
