Lesson 2: Wave motion

The wave: It is the disturbance that propagate and

transfers energy in the direction of propagation.

motion:

The flame of the candle vibrates (why)?
Because the particles of the air between the

vibrated candle and the tuning fork vibrate through

the tube.

Conclusion:

WAVE MOTION:

It is the total movement of the particles of the medium in a

certain moment with a definite direction.

LINE OF WAVE PROPAGATION:

The direction of progression of the wave

According to the direction of vibration of medium particles relative to the
direction of propagation:
