Application +4 | -1

A thin prism of angle

15^\circ

made of glass of refractive index

{\mu _1} = 1.5

is combined with another prism of glass of refractive index

{\mu _2} = 1.75

. The combination of the prisms produces dispersion without deviation. The angle of the second prism should be

View answer and explanation

Correct option: D

10^\circ

Option D (

10^\circ

) is correct because the angle of the second prism is calculated to produce dispersion without deviation, using the condition that the net deviation is zero.
