QUESTION - __________________ Define transverse waves and write two examples ? __________________

Answer 1

$\huge\underline{\overline{\mid{\bold{\red{ANSWER-}}\mid}}}$

TRANSEVERSE WAVE-

In this type of wave the particles move in a direction perpendicular to the direction of propagation.

• They do not cause any pressure variations in the medium in which they travel.
• They move through alternate crest and troughs.

For example, Radio wave, light wave.

Answer 2

A transverse wave is a moving wave whose oscillations are perpendicular to the direction of the wave or path of propagation. A simple example is given by the waves that can be created on a horizontal length of string by anchoring one end and moving the other end up and down.

Examples of transverse waves include:

• ripples on the surface of water.
• vibrations in a guitar string.
• a Mexican wave in a sports stadium.
• electromagnetic waves – eg light waves, microwaves, radio waves.
• seismic S-waves.
