Question

What do you mean by wavelength, frequency, amplitude, and the periodic time of a sound wave? Which of the mentioned quantities does not change when sound passes through different media?

Accepted Answer

The distance between two consecutive compressions or two consecutive rarefactions is called the wavelength of a sound wave. It is denoted by lambda $' λ'$

The number of oscillations of the density of the medium or the number of vibrations produced by a particle of the medium at a place per unit of time is called the frequency of the sound wave.

The maximum disturbance of the particles in the medium on either side of the mean position is called the amplitude of the wave.

The time taken to complete one oscillation of the density of the medium is called the time period of the sound wave or the periodic time.

Frequency remains unchanged when sound passes through different media.
