As light enters from air into glass slab, its wavelength

A student performs an experiment with glass slab to trace the path of a ray of light entering from air into glass slab and emerging into air again. On looking carefully at the trace abtained on paper, he will observe that the emergent ray and the incident ray :

A monochromatic ray of light passes from air to glass. The wavelength of light in air is lamda , the speed of light in air is c and in glass is V. if the refractive index of glass is 1*5 , write down (a) the relationship between c and V, (b) the wavelength of light in glass.

When light enters from water to glass what is the change in its velocity?
