A mirror works on the principle of
and a lens works on the principle of

A mirror works on the principle of reflection. This law states that :

Angle of the incidence is equal to the angle of reflection.

The incident ray, the reflected ray, the normal and the point of incidence all lie in the same plane.

Hence, the correct option is (B).

A lens works on the principle of refraction of light. This law states that :

where sin i is the sine of angle of incidence and sin r is the sine of angle of refraction.

The incident, reflected, normal all lie in the same plane.

Hence, the correct option is (A).

Explanation:

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
