Question

how are angles of incidence,angle of prism,angle of emergence and angle of deviation related to each other.​

Answer 1

Answer:

hope it will help you❤❤

Explanation:

Relation between angle of incidence and angle of emergence :

i+e=A+δ

where i= is the angle of incidence

e= is the angle of emergence

A= is Prism Angle

δ= is deviation angle

when angle of incidence is equals to angle of emergence (i=e) then prism will be in the minimum deviation position.

Answer 2

$\red{\mid{\underline{\overline{\textbf{Answer}}}\mid}}$

Emergent ray - is the ray which comes out of a medium after getting refracted inside it.

Angle of emergence - is the angle between emergent ray and the surface of prism from which it comes out.

Angle of incidence is the angle between the surface of prism and incident ray.

Angle of prism is the angle between two surfaces of prism.

Angle of deviation is the angle by which an incident ray gets deviated from its path after refraction.

$\red{\mid{\underline{\overline{\textbf{Relation :-}}}\mid}}$

Relation between angle of prism, angle of emergence,angle of deviation and angle of incidence is given by the expression :

$i + e = a + δ$

In this equation :

• I = angle of incidence
• e = angle of emergence
• a = angle of prism
• δ= angle of deviation

Thus the relation is : Sum of angle of incidence and angle of emergence = sum of angle of prism and angle of deviation.
