Description: The most common medium that allows us to hear sounds around us is air. But did you know that temperature, humidity and wind can also affect the speed of sound waves?

Question

Define the following terms :
(a) wavelength, (b) amplitude, (c) frequency, (d) time period, (e) wave velocity

Accepted Answer

(a) wavelength:- The linear distance between two consecutive compressions or two consecutive rarefactions is called wavelength. Wavelength is represented by letter $λ$ (Greek letter-lambda). Its SI unit is metre (m).

(b) amplitude:- The magnitude of the maximum displacement of vibrating particles of the medium on either side of their mean position is called amplitude. It is represented by the letter A. Its SI unit is metre.

(c) frequency:- The number of oscillations or vibrations produced in one second is called as frequency. The frequency is represented by $ν$ (nu). The SI unit of frequency is hertz (symbol Hz) where $1 Hz$ is one oscillation per second.

(d) time period:- The time interval between two consecutive compressions or rarefactions to cross a point is called time period. This period is represented by the letter T. Its SI unit is second (s).

(e) wave velocity:- The velocity with which the wave propagates in a medium is known as wave velocity. It is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.
