Question

Define :
1.Angle of Refraction
2. Angle of Incidence
3. Angle of Reflection
4. Angle of Glancing

Answer 1

Definition of angle of refraction

: the angle between a refracted ray and the normal drawn at the point of incidence to the interface at which refraction occurs

Definition of angle of incidence

: the angle that a line (such as a ray of light) falling on a surface or interface makes with the normal drawn at the point of incidence

Definition of angle of reflection

: the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface

Definition of glancing angle

: the angle between an incident beam (as of X rays or electrons) and the surface upon which it is incident : the complement of the angle of incidence

hope this helps you//

Answer 2

HEY MATE
THERE'S THE DEFINITIONS-

1.Angle of refraction
angle between the reflected ray and normal.

2.Angle of incidence
angle between the incident ray and normal.

3.angle of reflection
angle between the reflected ray and normal.

4.angle of glancing
angle between the incident ray and the surface.
