A ray of light with wavelength 5000 nm travelling from a medium with refractive index `(3/2)` suffers partial reflection and refraction in a medium of refractive index `(4/3)`. Find wavelength of reflected and refracted ray.

Explanation

Med.1 `lambda_1=500 nm , v_1=c/mu_1 , f=v_1/lambda_1`
Med. 2 `f=v_1/lambda_1=v_2/lambda_2, v_2=c/mu_2`, putting values we get `lambda_2`=5625 nm
