Ray incidents at `60^(@)` and reflected ray gets completely polarized, then speed of refracted light in denser medium is ......

A

`sqrt(2)`

B

`sqrt(3)xx10^(8)`

C

`sqrt(3)`

D

`sqrt(2)xx10^(8)`

Text Solution

Verified by Experts

The correct Answer is:
B
`n=tan theta_(p)=tan60^(@)`
`(c)/(v)= sqrt(3)`
`:. v=(c)/(sqrt(3))=(3xx10^(8))/(sqrt(3))=sqrt(3)xx10^(8) ms^(-1)`
