Question

difference between pulse and mechanical wave​

Answer 1

Answer:

A pulse is more time-space confined, while a wave, if not explicitly specific, is more of a spreading state. So, a pulse usually has a spectum distribution to maintain its confined profile, and it may have different so-called modes in its time-space distribution. These modes may change during its propagation of the pulse.

Another thing, if the amplitude of the wave and the pulse under consideration were the same, let’s say a large amplitude, the pulse will do less harm to the media as its lacking of a continuous stimuli to the media. Most of the spectacular phenomena spotted with laser-material interations are based on this fact.

Answer 2

• A single sudden change in a property of a medium or a quantity is known as a pulse, whereas waves are repeated oscillating changes in the properties or the quantity.

• A pulse has a sharp rise and a sharp decline of amplitude, whereas a wave can be either regular or irregular. The shape of the wave throughout a period is known as waveform.

• A wave can be considered as a series of pulses.
