Question

A pulse is a wave:

  1. Of high duration
  2. Of short duration
  3. Which travels in a vacuum only
  4. Which travels in solids only

hintHint:

Pulse wave is a short duration of wave

The correct answer is: Of short duration


    Pulse wave is due to a sudden non persistent vibration of the source hence it is short duration wave
