A light ray going through a prism with the angle of prism `60^@,` is founded to deviate at least by `30^@.` what Is the range of the refractive index of the prism?

A

`lesqrt2`

B

`gesqrt2`

C

`gesqrt3`

D

`lesqrt3`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Given, A=`60^(@)` and `delta_(m)=30^(@)`
`therefore` Refractive index of prism, `mu`=`(sin((A+delta_(m))/2))/sin(A/2)=sin45^(@)/(sin30^(@))=sqrt2`
