12. Matter wave associated with a moving partucie is (a) a finite monochromatic wave train having velocity less than that of light (b) an infinite monochromatic wave train having a phase velocity greater than that of light (c) a wave packet having group velocity equal to that of the moving particle (d) a wave packet having phase velocity equal to the group velocity 13. Uncertainty principle is the consequence of (a) wave nature o dl particle-particle interaction (a) wave nature of the particle (6) particle nature of wave (C) wave particle duality 14. Uncertainty principle tells that (a) a particle can have only momentum but position is uncertain (b) a particle can have only position but momentum is uncertain (c) one can determine simultaneously both position and momentum accurately (d) one can not determine simultaneousily both position and momentum accurately 15. For a heavy particle, according to uncertainty relation (a) ArAv, = h (b) ArAv, =0 (c) ArAv, =D (d) ArAv, = 16. An electron is confined in atom of diameter~1A. According to uncertainty principle, (a) APi6.62x10"kg m/s (b) AP6.62x 10 kg m/s (c) APmi 6.62x10kg m/s (d) Ax,=10"m. 17. For a particle moving with velocity v <
