Question

Explain the following terms:

a) amplitude

b) wavelength

c) frequency

Answer 1

Amplitude : It is defined as the maximum displacement produced in the vibrating particle on either side of the mean position. It is denoted by A. Its SI unit is metre.

Wavelength : It is defined as the distance travelled by a wave during the time a particle of the medium completes one vibration. It is denoted by k. Its SI unit is metre.

Frequency: It is the number of occurrences of a repeating event per unit of time. Its SI unit is Hertz (Hz).
