The wavelenght of sodium light in air is 5890Å. The velocity of light in air is `3 xx 10^(8) ms^(-1)` The wavelenght of light in a glass of refractive index 1.6 would be close to

A

5890Å

B

3681Å

C

9424Å

D

15078Å

Text Solution

Verified by Experts

The correct Answer is:
A, C
`mu = (lambda_(a))/(lambda_(g)) rArr lambda_(g) = (lambda_(a))/(mu) = (5890Å)/(1.6) = 3681Å`
