The wavelength of green light in air is ...

The wavelength of green light in air is 5400 A.U. Its wavelength in the glass of refractive index 3/2 is

A

a. 5400Å

B

b. 2700 Å

C

c. 3600 Å

D

d. 8100 Å

Text Solution

Verified by Experts

The correct Answer is:
C
`n=(V_a)/(V_g)=(n lambda_a)/(n lambda_g)=(lambda_g)/(lambda_g)`
`:. lambda_g=(lambda_a)/(n)=(5400)/(3//2)=3600Å`
