A light passing through air has wavelength $6000 \overset{˚}{A}$ . The wavelength when same ray passes through a glass slab of refractive index 1.5 will be :

Options:

Answer:

Solution:

When light ray passes through a glass slab, then new wavelength $λ^{'} = \frac{λ}{μ} = \frac{6000}{1.5} = 4000 \overset{˚}{A}$
