Refraction In A Medium With Varible Refractive Index

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.

If angle of incidence is twice the angle of refraction in a medium of refractive index mu , then angle of incidence is

A converging lens of refractive index 1.5 is kept in a liquid medium having the same refractive index. What would be the focal length of the lens in the medium ?

A ray of light travels from a medium of refractive index n_(1) to a medium of refractive index n_(2) . If angle of incidence is i and angle of refraction is r, than (sin i)/(sin r) is equal to
