Wave Motion

51. Wave motion in a material medium involves (a) the propagation of a disturbance, (b) interparticle interactions, (c) the transfer of energy, (d) all of the preceding.

52. For a periodic wave propagating with a speed v, the following relationship holds: (a) l = v/f, (b) v = l/f, (c) f = lv (d) vf = l

53. What type(s) of wave(s) will propagate in (a) solids, (b) liquids, and (c) gases?

54. A longitudinal sound wave has a speed of 340 m/s in air. If this produces a tone having a frequency of 4.0 x 10³ Hz, what is the wavelength?

55. A transverse wave has a wavelength of 0.50 m and a frequency of 40 Hz. What is the wave speed?
