In internal reflection light reflects from which medium to which medium?

What is reflection of light ?

Total internal reflection takes place when light moves from a medium P to a medium Q where P & Q have the following characteristics?

In total internal reflection_____

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

wavelength of light in a medium is 4000 Å and that in another medium is 6000 Å . What will be the critical angle if light ray moves from first medium to second medium?

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

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

State law of reflection of light.

When light travels from a rarer medium to a prism which is a denser medium, light ray bends towards the base of the prism. Is the statement true of false?

The law of reflection of light are valid for-
