Question

laws
of Reflection & Refraction​

Answer 1

Answer:

There are three laws which govern Reflection and Refraction. These can be very easily derived from geometry.

They are:

Angle of Incident Ray with Normal

(i) EQUALS Reflected Ray with Normal(r).(i=r)

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.
