There is a equilateral prism of refractive index `3` on which a light ray is incident normally on one face as shown in the figure. Find the length of the path traveled by the light ray inside the prism.

`sqrt(3)(L)/(2)`

`sqrt(3)L`

`3L//2`

`L`

Text Solution

Verified by Experts

Length of path `=sqrt(3)x+(L-2x)(sqrt(3))/(2)`
`(sqrt(3)L)/(2)`
