5. A monochromatic light wave is incident normally on a glass slab of thickness d, as shown in the figure. The refractive index of the slab increases linearly from ni to n2 over the height h. Which of the following statement(s) is(are) true about the light wave emerging out of the slab? Monochromatic light wave (n-n)d (A) It will deflect up by an angle tan 2h (B) It will deflect up by an angle tan (n2-n)d h n2 h n > n ni d (C) It will not deflect (D) The deflection angle depends only on (n2 - n) and not on the individual values of n and n 6. An annular disk of mass M, inner radius a and outer radius b is placed on a horizontal surface with coefficient of friction , as shown in the figure. At some time, an impulse Jo is applied at a height h above the center of the disk. If h = hm then the disk rolls without slipping along the x-axis. Which of the following statement(s) is (are) correct? Jo L. (A) For 0 and a 0, hm = b/2 (B) For 0 and a b, hm = b (C) For h = hm, the initial angular velocity does not depend on the inner radius a (D) For = 0 and h = 0, the wheel always slides without rolling 7.
