Question

At resonance, which of the following is maximum
(A) Frequency (B) Wavelength (C) Velocity D) Amplitude​

Answer 1

Amplitude is maximum at resonance.

Option (d) is correct.

Explanation:

• Resonance is a vibration of maximum amplitude.
• The measure of change in a period during the periodic variable is called amplitude.
• Thus the amplitude is the maximum distance from the equilibrium position.
• It is one-half of the total length of a wavelength and it can be either the top or bottom part of the wavelength from the equilibrium position.
