Question

ترا
Desive an expression for wavelength, frequency and
Velocity of sound.​

Answer 1

Answer:

Derive an expression of wave velocity in terms of frequency and wavelength of the wave. Since the distance equal towavelength (λ) istrav-elled by the wave in a time equal to the period of vibration (T) of the particle of the medium, we have.

Answer 2

Answer:

Derive an expression of wave velocity in terms of frequency and wavelength of the wave. Since the distance equal to wavelength (λ) istrav-elled by the wave in a time equal to the period of vibration (T) of the particle of the medium, we have

Explanation:

A wave has a wavelength λ, which is the distance between adjacent identical parts of the wave. The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ. The time for one complete wave cycle is the period T. The number of waves per unit time is the frequency ƒ.
