Question

If the wavelength of light in air is 7200 A, then the wavelength of same light in the glass is?

Answer 1

wavelength of light in glass = 1.5
according to given formula-----------

refractive index of Glass = wavelength of light in air / wavelength of light in medium X



1.5 =7200A/ wavelength of light in glass
therefore, wavelength of light in glass =4800A

Answer 2

Answer:

4/3lambda1/lambda2
