Suppose you look through a 3.3 mm thick window comprised of a material whose refractive index is 1.63.
(a) Find by what time interval is the light you see delayed by having to go through glass instead of air?
(In seconds)
(b) Find by how many wavelengths is it delayed, if its vacuum wavelength is 600nm?
(In wavelengths)
