Question

Bouncing back of light in the same medium is called (refraction , reflection , rarefaction , retardation)

Answer 1

Bouncing back of light in the same medium is called reflection.

Answer 2

Bouncing back of light into the same medium is called reflection. (option 2)

• Reflection is the process by which light rays bounce back after striking a surface into the same medium.
• The light ray strikes the plane surface such as a mirror with an angle 'i' called the angle of incidence. It is then reflected from that surface with an angle of reflection 'r' that is equal to 'i'.
• This obeys the First Law of reflection of light. The second law tells us that the incident ray, refracted ray and the normal plane lie on the same plane at the point of incidence.
