Question

MCO: Angle which is formed between normal ray and ray entering a medium is known as
critical angle
angle of incidence
angle of reflection
angle of refraction
D​

Answer 1

Answer:

Angle of incidence

Explanation:

angle of incidence is the angle made by incident ray with the normal to the surface on which it is striking..

hope it helps

thank you

Answer 2

ANGLE OF INCIDENCE (option a)

Since the ray of light is entering one media from another medium, we can consider this phenomenon to be refraction.

Now, the ray entering the second medium is actually known as the incident ray.

• The angle between the normal and the incident ray is also known as the angle of incidence.

• It is denoted as $\angle i$

So, first option is correct.
