A prism of refractive index sqrt2 has refractive angle `60^@.` In the order that a ray suffers minimum deviation it should be incident at an angle of

A

`45^@`

B

`90^@`

C

`30^@`

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
At minimum deviation,
`r_1=r_2=A/2=30^@`
Now `mu=(sini_1)/(sinr_1)` or `sqrt2=(sini_1)/(sin30^@)`
We get `i_1=45^@`
