Question

Calculate the wave length of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium​

Answer 1

Answer:

Frequency of the sound wave, ν= 220 Hz

Speed of the sound wave, v = 440 m s-1

For a sound wave,

Speed = Wavelength x Frequencyv = λ x ν

ˆ´ λ= v / ν = 440 / 220 = 2m

Hence, the wavelength of the sound wave is 2 m.

Answer 2

Answer:

Wavelength of the sound wave in a given medium is 2 m.

Explanation:

Given:

• Speed of the sound wave = 440 m/s.
• Velocity of the sound wave = 220 Hz.

To find:

Wavelength of the sound wave.

Solution:

We know that,

Wavelength = Velocity/Frequency

λ = v/f

=> λ = 440/220

= 2 m.

Thus, required wavelength is 2 m.
