Question

why normal ray incedence ray and reflected ray all lie in the same place (give reason)?​

Answer 1

Answer:

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.

Hope it helps

Answer 2

Answer:

From the laws of reflection, we know that

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