Question

Define the following terms in relation to a wave:

(a) amplitude

(b) frequency

(c) wavelength

(d) wave velocity

Answer 1

(a) Distance between the resting position and the maximum displacement of the wave is known as amplitude.

(b) Number of waves passing by a specific point per second is called frequency.

(c) In one time period of vibration of the particle of the medium, the distance travelled by a wave is called wavelength

(d)The distance travelled in one second by the wave is called its wave velocity.
