Question

derive relation between frequency, wavelength and speed of sound wave​

Answer 1

Answer:

Derive a relation between wavelength, frequency and velocity of a wave. Frequency, wavelength and wave velocity are related as follows: Wavelength is the distance travelled by the wave during the time a particle of the medium completes one vibration

Answer 2

Answer:

ν = n λ

Explanation:

Let,

the frequency of a sound of sound be n. That means the number of vibrations performed by it in 1 second is n.

The distance travelled by a wave during one vibration of sounding body is called wavelength.

Let it be λ . The distance travelled by the wave during n vibration performed by the body is nλ.

By definition of frequency, these n vibrations are performed in 1 second. Hence the distance travelled by the wave in 1 second is nλ

The distance travelled by the wave in 1 second is called velocity () 0f the wave

                                ∴  ν = nλ

This is the relation of velocity of the wave, frequency and wavelength.
