Question

calculate the wavelength of a sound wave whose frequency is 820 HZ and speed is 440m/s in a given medium​

Answer 1

Answer:

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

Solution:9. 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.
