The wavelength of light diminishes `mu` times (`mu=1.33` for water) in a medium. A diver from inside water looks at an object whose natural colour is green. He sees the object as

A diver in water looks obliquely at an object AB in air. Does the object appear taller, shorter or of the same size to the diver?

The wavelength of light in a medium is lamda=lamda_0/mu where lamda is the wavelength in vacuum. A beam of red light (lamda_0=720 nm) enters into water The wavelength in water is lamda=lamda_0/mu=540 nm. To a person under water does this light appear green?

Light is incident from glass (mu = 1.50) to water (mu = 1.33) find the range of the angle of deviation for which there are two angles of incidence.
