DIFFERENCE BETWEEN A PULSE AND A PERIODIC WAVE FOR CLASS 9 PHYSICS

What is the differences between a Pulse and a Periodic wave ?

DISTINGUISH BETWEEN A PULSE AND A PERIODIC WAVE

PULSE

1. The wave set up by a single disturbance in the medium is called a pulse.
2. A pulse is a wave of short duration.
3. A pulse is not repetitive.
4. A pulse is formed in a small part of the medium.So, in the formation of a pulse, only a part of the medium is displaced from its original undisturbed position.
5. When a pulse is formed, the medium oscillates or vibrates for a short while and then returns to its original undisturbed position.

PERIODIC WAVE

1. The wave set up by continuous disturbance in the medium occurring due to regular vibration is called periodic wave.
2. A periodic wave is a continuous wave of long duration.
3. A periodic wave is repetitive. A periodic wave has a basic pattern which repeats itself after a fixed interval.
4. A periodic wave stretches over the entire length of the medium. So, in the formation of a periodic wave, every point of the medium is displaced.
5. When a periodic wave is formed, the medium oscillates or vibrates for a long time after it is disturbed.
