Standing waves are formed on a string when interference occurs between two waves having

Options

  1. Athe same amplitude travelling in the same direction with no phase difference between them
  2. Bthe same amplitude, travelling in the opposite direction with no phase difference between them
  3. Cdifferent amplitudes travelling in the same direction
  4. Ddifferent amplitudes travelling in the opposite direction

Correct answer

B. the same amplitude, travelling in the opposite direction with no phase difference between them

Step-by-step solution

When two identical transverse or longitudinal progressive waves travel in a bounded medium with the same speed, but in opposite directions, then by their superposition a new type of wave is produced which appears stationary in the medium. Thus, is called stationary wave.
