what is meant by angle of incidence and angle of reflection
Answers
Answer:
At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. ... The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.
The ray of light that hits the polished surface is called the incident ray.
The ray that gets reflected away is called the reflected ray.
The point at which the light hits the surface is called the point of incidence.
If a line is drawn perpendicular to that point, it is called the normal.

What is Angle of Incidence?
The incident ray and reflected ray form two angles at the point of incidence:
The angle formed between the normal and the incident ray at the point of incidence is called the angle of incidence.
Similarly, the angle formed between the normal and the reflected ray at the point of incidence is called the angle of reflection.
What is the relationship between angle of incidence and angle of refraction?
When light passes from one medium to another with different densities, its path gets deviated. This phenomenon is called the refraction of light. Like a reflection, there are similar components in refraction too. They are:
Incident ray
Refracted ray
Normal
Point of incidence
The angle formed at the point of incidence between the incident ray and the normal is called the angle of incidence. And the angle formed between the refracted ray and the normal is called the angle of refraction.
