Find the speed of light of wavelength `lambda =780nm` (in air) in a medium of refractive index `mu=1.55.`
(b) What is the wavelength of this light in the given medium ?

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D

(a) (` v=c/mu=(3.0xx10^8)/1.55=1.94xx10^8m//s`
(b) `lambda_("medium")=(lambda_("air"))/(mu)=780/1.55=503nm`
