Question

2. What is reflection ? Do all surfaces reflect light?​

Answer 1

Answer:

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface.

Answer 2

Answer:

The throwing back by a body or surface of light, heat, or sound without absorbing it is called reflection. No all surfaces don't reflect light.
