Question

Represent graphically by two separate diagrams in each case

(i) Two sound waves having the same amplitude but different frequencies.

(ii) Two sound waves having the same frequency but different amplitudes.

(iii) Two sound waves have different amplitudes and also different wavelengths.

Answer 1

Amplitude: Amplitude is the maximum displacement or distance moved by a point on a vibrating body or wave measured from an equilibrium position.

The equation representing a vibration:

$x=A\sin \left(\omega t+\varphi \right)$

$x$= displacement

$A$= amplitude

$\omega$= angular frequency

$t$= time

$\varphi$= phase difference

Frequency: Frequency refers to the number of cycles in a particular unit of time.

The formula of frequency:

$f=\frac{1}{T}$

$f$= frequency

$T$= period
