Question

what is the law ofwhat is the law of reflection reflection

Answer 1

Answer:-

◆law of reflection

(1) the angle of incidence is equal to the angle of reflection

(2) the incident ray ,the normal and the reflected ray all lie on the same plane

◆law of refraction

(1) the incident ray , the retracted ray and normal all lie on same plane

(2) the ratio of sine of angle of incidence to the

sine of angle of refraction is a constant

this law is known as Snell's law of refraction

sin i / sin r = constant

Answer 2

$\huge\bold\blue {\mathfrak{answer:}}$

Laws of reflection are:

(i) The incident ray, the reflected ray and the normal ray at the point of incidence, lie in the same plane.

(ii) The angle of incidence is equal to the angle of reflection.
