When a ray of light passes from air medium to denser medium then the refractive index is

When a ray of light passes from air medium to denser medium then its speed and wavelength

The ray of light travels from raer medium to denser medium of refractive index mu . The angle of incidence of twice the angle of refraction. The angle of incidence is given by

A ray of light passes from solid medium 1 into solid medium 2. The refractive index of medium 1 is the same as that of medium 2. Which of the figures correctly shows the path of the ray of light in the two mediums?

When a ray of light from air enters a denser medium, it :

When light passes from a denser medium to a rarer medium

A ray of light passes from denser medium to rarer medium a. What happens to the refracted ray as the angle of incidence increases from 0^(@) ? b. What is the importance of the angle C (marked in the figure above )? c. How is 'C' related to the refractive index 'n' of the medium ? Explain.
