How does light reflect?
Asked by jmbhuvana | 19 Dec, 2018, 09:31: PM
Expert Answer
Light gets reflected from any opaque surfaces. When the light ray is incident on the opaque surfcaes the angle of incidence is equal to angle of reflection. 
When the light rays are incident on rough surfaces it undergoes irregular reflection and when the light rays are incident on polished or smooth surfaces they undergoes regular reflection.
