A ray of light incident on face `AB` of an equilateral glass prism, shows minimum deviation of `30@` .Calculate the speed of light through the prism.

A

`2.121xx10^(8)ms^(-1)`

B

`1.50xx10^(8)ms^(-1)`

C

`1.25xx10^(8)ms^(-1)`

D

`1.75xx10^(8)ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`mu=(sin(A+D)/2)/(sin(A/2)), mu=C/C_(med)`
