A light ray, going through a prism with the angle of prism `60^@`, is found to deviate by ` 30^@`. What limit on the refractive index can be put from these data ?

Answer

B

Explanation

For the given data
`Refractie index `(mu)le(sin((60+30)/2))`
`(sin(60/2))`
`i.e., mule(sin45^@)/(sin30^@)`
i.e., `mule(1/sqrt2)/(1/2)`
`i.e, muc,=sqrt2`
