Answer:
Explanation:
1. The waves in which the partciles of medium vibrates in the same direction of propagation of wave, are called longitudinal waves.
The waves in which the partciles of medium vibrates in the perpendicular direction of propagation of wave, are called transverse waves.
2. Period, T = 0.03 s
The frequency is given by the reciprocal of the period.
[tex]f=\frac{1}{T}\\\\f =\frac{1}{0.03}\\\\f = 33.3 Hz[/tex]
