Question

explain the laws of reflection and refraction also?

Answer 1

Answer:

$\huge\underline\bold\red{Answer!!}$

The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray.

Answer 2

Laws of Reflection and Refraction:-

• Popularly known as SNELL'S LAW it is n1*sin i=n2*sin e where i is same as above,e is angle of refracted beam with normal.
• The INCIDENT ray,REFLECTED ray, REFRACTED ray and the NORMAL at the point of incidence all lie in the same plane.
• The plane is referred as plane of incidence.
