An equilateral prism of refractive index mu = (4)/(sqrt(3)) is kept in a medium of refractive index mu_(1) . Consider a light ray to be normally incident on one of the refracting faces. The diagram shows variation of magnitude of angle of deviation (beta) with respect to mu_(1) . (a) Find value of k_(2) . (b) Find value of k_(1) .

When a monochromatic light ray is incident on a medium of refracive index mu with angle of incidence theta_(1) ,the angle of refraction is theta_(r). if theta_(i) is changed slightly by Deltatheta_(i) ,then the corresponding change in theta_(r) will be-

A converging beam of light is incident on a right angled isosceles prism as shown in the Figure. The marginal rays in the beam are incident at angle +- theta . The refractive index for the glass of the prism is mu = 1.49 (= (1)/(sin 42°)) . Find the maximum value of theta for which no light comes out of the hypotenuse surface.

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.

A ray of light, travelling in a medium of refractive index mu, is incident at an angle i on a composite transparent plate consisting of three plates of refractive indices mu_1,mu_2 and mu_3. The ray emerges from the composite plate into a medium of refractive index mu_4, at angle x. Then,
