The refractive index of glass is 1.5 for...

The refractive index of glass is 1.5 for light waves of `lamda=6000` Ã… in vacuum. Its wavelength in glass is

A

2000 Ã…

B

4000 Ã…

C

1000 Ã…

D

3000 Ã…

Text Solution

Verified by Experts

The correct Answer is:
B

`mu=(c)/(v)=(lambda_(v))/(lambda_(g))`
` :. lambda_(g)=(lambda_(v))/(mu)=(6000)/(1.5) = 4000Ã…`
