Question

The amplitude of a wave is:

• A. The distance the wave moves in one time period.
• B. The maximum distance moved by the particles on either side from the mean position.
• C. The maximum distance between the extreme positions moved by the particles.
• D. The distance equal to one wavelength.

Answer 1

The correct option is B The maximum distance moved by the particles on either side from the mean position.

The amplitude of a wave is the distance between the mean position and the extreme position of an ocillating particle. In other words, it is the distance moved by the particles on either side from the mean position.
