If wavelenght of light in air is `2400 xx 10_(-10)` m, then what will be the wavelenght of light in glass `(mu = 1.5)`?

A

1600 Å

B

7200 Å

C

1080 Å

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
` mu = (lambda_(a))/(lambda_(g)) rArr lambda_(g) = (lambda_(a))/(mu) = (2400 xx 10^(-10))/(1.5) = 1600 Å`
