Question

FIND REFRACTIVE ANGLE OF A GLASS PRISM IF RAY OF LIGHT WHICH IS INCIDENT AT ANGLE 27 DEGREE 30 MINUTES ON ONE OF IT'S REFRACTING FACE EMERGES PARALLEL TO THE OTHER​

Answer 1

Answer:

Angle of incidence, i=45

0

Angle of prism, A=60

0

Angle of minimum deviation, δ

m

=2i−A=30

0

Answer 2

Explanation:

Angle of incidence, i=45

Angle of prism, A=60

Angle of minimum deviation, 6 =2i-A=30 sin

A sin( 2 A+6 sin 30 sin 4522)
