Bihar Police Constable Model Paper 4

CONCEPT:

• Amplitude (A): The maximum amount of displacement of the medium particles from its mean position is called the amplitude of the wave.

• Frequency is the number of oscillations per second and is expressed in hertz.
• The amplitude of vibration is measured by displacement from the mean position.

EXPLANATION:

• The amplitude of vibration is the maximum displacement from the mean position. So option 1 is correct.
