An equilaterial prism produces a minimum deviation of `30^@`. The angle of incidence is.

A

`30^@`

B

`60^@`

C

`45^@`

D

`90^@`

Text Solution

Verified by Experts

The correct Answer is:
C
For equilaterial prism,
`A= 60^@, delta_m = 30^@`
As `2 i= A + delta_m = 60^@ + 30^@ = 90^@`
`:. i= (90^@)/(2) = 45^@`.

An equilateral prism produces a minimum deviation of 30^(@) . The angle of incidence is

An equilateral glass prism can produce a minimum deviation of 30° to the path of an incident ray. A transpar- ent slab of refractive index 1.5 is placed in contact with one of the refracting faces of the prism. Thickness of the slab is 3 cm. Now calculate the minimum possible deviation which can be produced by this prism-slab combination.

A prism has a refracting angle of 60^@ . When placed in the position of minimumm deviation, it produces a deviation of 30°. The angle of incidence is,
