transverse wave

Question 1 What are transverse waves?

Question 2 What is crest?

Question 3 What is trough?

Question 4 Give examples of transverse waves?

Transverse Waves
A wave in which the particles of medium vibrate up and down at right angle to direction in which wave is moving is called transverse wave.

Transverse wave can be produced only in solid and liquids but not in gases.
Transverse wave is one in which individual particles of medium move about their mean position in a direction perpendicular to the direction of wave propagation.

For Ex:

1)The wave produced by moving one end of long spring up and down rapidly,whose other end is fixed.
2)The water waves or ripples formed on the surface of water in a pond.

When a transverse wave travels horizontally in a medium,the particles of medium vibrate up and down in vertical direction.

wave

When the vibrating particle move upward,above the line of zero disturbance,they form elevation or hump(crest)and when they move downward,they form depression or hollow(trough).

Transverse waves consist of trough and crest.
Transverse wave is represented graphically by plotting the displacement of different particles of medium from line of zero disturbance against distance from the source.
