1. According to Schrodinger, a particle in motion is equivalent (a) a single wave (6) a wave packet (d) either (b) or (c) (C) a group wave 2. For a relativistic particle moving with velocity v, its phase velocity is (a)v (b) v/2 (C) cv (d) v/c 3. For a relativistic particle moving with velocity v, the group velocity Vg IS same as (a) particle velocity (v) (b) phase velocity (v) (d) velocity of light (C) (C) wave velocity (V) 4. The interference of waves associated with a beam of electrons can be demonstrated by means of a (a) single slit experiment (C) Crystal grating experiment (6) double slit experiment (d) None of these 5. In 1927 Davisson and Germer demonstrated experimentally and verified de Broglie's relation for the wavelength of a/an (a) proton (b) neutron (C) photon (d) electron 6. The de Broglie matter wave is a (a) monochromatic wave (D) polychromatic wave (C) standing wave (O) wave packet 7. Phase velocity and group velocity are equal when the medium is (a) dispersive (b) non-dispersive (C) isotropic (d) homogeneous 8. For a relativistic particle, the relation between phase velocity (,) and group velocity (Y) is (a) v, =Vg/c (c) V,C/Vg (6) V vc (d) v =V,+c 9. Davisson-Germer experiment suggests that the electron is (b) a wave (a) a particle (C) partly wave and partly particle (d) none of them 10. In Davisson-Germer experiment with electron beam and nickel crystal, the maximum diffraction appears at (a) 45" with 50 volts (6) 50 with 54 volts (c) 54 with 50 volts (d) 60" with 75 volts 11. Davisson-Germer experiment proved that if be the de Broglie wavelength and V be the accelerating voltage, then (a) ov (b) 2 ocl/V ) 2 oc V (d) A c1/V
