For total internal reflection to take place, the angle of incidence `i` and the refractive index `mu` of the medium must satisfy the inequality

Under what conditions is the phenomenon of total internal reflection between the critical angle of incidence and the refractive index of the medium.

Light traveling from a transparent medium to air undergoes that internal reflection at an angle of incident of 45^(@) . Then refractive index of the medium may be

A ray of light is incident on a medium at an angle i. It is found that the reflected ray is at right angles to the refracted ray . The refractive index of the medium is given by

A monochromatic light is incident on the plane interface AB between two media of refractive indices mu_(1) and (mu_(2)gtmu_(1)) at an angle of incidence theta as shown in Fig. The angle theta is infinitesimally greater than the critical angle for the two media so that total internal reflection takes place. Now, if a transparent slab DEFG of uniform thickness and of refractive index mu_(3) is introduced on the interface (as shown in the figure), show that for any value of mu_(3) all light will ultimately be reflected back into medium II.
