Question

The the refraction of a white light through prism is shown below identify the angles p q r​. one who
answers correct will be praised

Answer 1

Explanation:

the refraction of a white light through a glass prism is shown below identify the angles P Q R and S

Answer 2

P is the angle of incidence.

Q is the angle of prism.

R is the angle of emergence.

Refraction through prism:

• When a ray of light passes through a prism, it gets refracted and deviates from its actual path.
• The refracted ray emerges after coming out of the prism.
• P is the angle made by incident ray with the normal and is called angle of incidence.
• Q is the angle made by two faces of prism and is called angle of prism.
• R is the angle made by the emergent ray with the normal and is called the angle of emergence.
