Question

What is meant by "reflection of light"? Define the following terms used in the
study of reflection of light by drawing a labelled ray diagram.
A)Incident ray
B) Point of incidence
C)Normal
D) Reflected ray
E) Angle of Incidence
F)Angle of reflection​

Answer 1

Answer:

refraction of light - refraction is the change in direction and speed of a light ray when passes from one medium to another.

a) is the path taken by light from the source which strikes and gets reflected at the interface/boundary.

b) The point on the surface where the incident ray strikes the surface is called the point of incidence. 

c) is the path taken by a ray that is perpendicular to the interface/boundary.

d) is a ray that passes through an interface between two media and travels into the medium on the other side of the interface.

e) is the angle between the incident ray and the normal.

f) is the angle between the normal and the refracted ray.
