Define the term time period and amplitude.

1.	Define the term time period and amplitude.
Answer» Time Period : (a) Time taken to complete one vibration is called time period. (b) Time required to pass two consecutive compressions or rarefactions through a point is called time period. • SI unit of time period is second (s). Time period is denoted by T. • The frequency of a wave is the reciprocal of the time period. V = 1/T Amplitude : The maximum displacement of the particle of the medium from their original undisturbed position is called amplitude of the wave. • Amplitude is denoted by A and its SI unit is metre (m).

Time Period :

(a) Time taken to complete one vibration is called time period.

(b) Time required to pass two consecutive compressions or rarefactions through a point is called time period.

• SI unit of time period is second (s). Time period is denoted by T.

• The frequency of a wave is the reciprocal of the time period.

V = 1/T

Amplitude :

The maximum displacement of the particle of the medium from their original undisturbed position is called amplitude of the wave.

• Amplitude is denoted by A and its SI unit is metre (m).
