Why is total internal reflection called total?

In total internal reflection_____

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

Why will not the total internal reflection take place if light travels from a rarer medium to a denser medium?

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?

If a ray of light moves from a _______ medium to a _________ medium, total internal reflection does not take place [Fill in the blank].

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?

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 .

What do you understand by total internal reflection?

A light ray is incident on a rarer medium from a denser medium. The velocity of light in rarer medium is double its value in denser medium. For total internal reflection what should be the value of the critical angle?
