• A wave traveling in a medium produces changes in pressure in the medium. The wave must be
    A) Transverse B) Longitudinal C) Stationary D) None of these
  • Particles A and B separated by 0.25 m differ in phase by π/4 and their state of vibration of A is same as that of B after a time of 0.025 s. The velocity of the wave is

  • A wave traveling in a medium produces compressions and rarefactions at a given place. If the compressions and rarefactions have a time lag of 0.05 s and if successive compressions are separated by 0.005 m the velocity of the waves is
