What is total internal reflection ?

A point source S is placed at the bottom of different layers as shown is figure,the refractive index of bottommost layer is mu_(0) The refractive index of any other upper layer is mu(n)=mu_(0)-(mu_(0))/(4pi-18) where n=1,2,..... A ray of light starts form the source S as shown. Total internal reflection takes place at the upper surface of a layer haing n equal to

Write the necessary conditions for the phenomenon of total internal reflection to take place. How does one account for the brilliance exhibited by a diamond when it is suitably cut ? 5

As shown in figure, a ray of light is incident on glass cube. If it experiences total internal reflection in vertical plane, then what is the refractive index of glass?

A parallel beam of light is incident from air at an angle alpha on the side of right angled triangular prism of refractive index mu = sqrt(2) . Light undergoes total internal reflection in the prism at the face PR when alpha has a minimum value of 45^@ . The angle theta of the prism is. .

At what angle should a ray of light be incident on the face of a prism of refracting 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.

When interference of light takes place

Assertion : The images formed by total internal reflections are much brighter than those formed by mirrorrs or lenses. Reason : There is no loss of intensity in total internal reflection.

Assertion:- Images formed by TIR (Total internal reflection) are much brighter than formed by mirrors or lenses. Reason:- IN TIR, there is no loss of intensity while in case of reflection from mirrors or refraction from plane surfaces or lenses there is some loss of intensity as all light can never be reflected or refracted.
