Question
Give some examples of waves which are combination of both transverse and longitudinal wave motion.
Solution
A wave has both transverse and longitudnal waves, when it propagates along the surface of a medium. The particles move either along a circle or an ellipse.
Examples of such waves are:
(i) Seismic waves travelling along the surface of the earth during an earthquake or explosion.
(ii) Ocean waves in deep water.
(iii) Wave pulses produced by beetle’s motion along the sand’s surface.
