Question

State the laws of reflection.​

Answer 1

Answer:

There r 3 types of laws of reflection. They are

The incident Ray, the refracted Ray and the normal to the interface of 2 transparent media at the point of incidence all lie in the same plane

• During refraction, light follows snells law
• n1sin i=n2 sin r (or) sin i/sin r = constant

Answer 2

Answer:

radhe radhe thank

Explanation:

rule 1 :- if an incident ray is parallel to the principal Axis then the reflected ray passes through the principal focus.

rule 2 :- if an incident ray passes through the principal focus of the mirror, the reflected ray is parallel to the principal axis.

rule 3 :- if an incident ray passes through the centre of curvature of the mirror, the reflected ray traces the same path back.
