Explain total internal reflection from law of refraction.

Write down the laws of refraction.

State the laws of refraction

A ray of light travelling in a transparent medium falls on a surface separating the medium from air at an angle of incidence of 45^(@) . The ray undergoes total internal reflection. If mu is the refractive index of the medium with respect to air, select the possible values (s) of mu from the following

At what angle should a ray of light be incident on the face of a prism of refractive angle 60^(@) so that it just suffers total internal reflection at the other face? The refractive index of the material of the prism is 1.524 .

Distinguish between the total internal reflection and reflection from a plane mirror.

Why is total internal reflection called total?

Refractive index of glass is 1.5 and that of water is 1.33. will total internal reflection takes place what will be the critical angle?

There is air above water. Total internal reflection may take place for a ray of light passing from water to air. If a glass slab is placed above water, is it possible for a ray to be totally reflected? Where will the total internal reflection take place?
