What happens to a ray of light when it travels from one medium to another having equal refractive index?

What will happen to the energy of light when it travels from rarer to denser medium?

Fill in the blanks:- When a ray of light travels from denser medium to rarer , the angle of refraction is _______ than the angle of incidence.

When a light ray travels from one medium to another and gets refracted, velocity of light becomes double. For total internal reflection in this condition, the value of critical angle is

In vacuum, speed of light is v_(0) , frequency is n_(0) and wavelength is lambda_(0) . When a ray travels from one medium to another, the above physical quantities become v,n and lambda respectively. mu is refractive index of the medium. Which of the following statements are correct?

What is the angle of incidence when light passes from vaccume to a medium of refractive index sqrt3 ? Angle of refraction is 30^@ . What is the angle of deviation in this case?

What is the refractive index of a medium?

What is the time taken by light to travel through a glass slab of thickness ‘d’ and refractive index mu ?

Establish the relationship between the relative refractive index of one medium with respect to another medium and their absolute refractive indices.

If frequency of light increases will there be any change in the refractive index of the medium?
