Question

25. Calculate the wavelength of a sound wave whose frequency s 220 Hz and speed is 440m/s in a
given medium
Ans Given,
Frequency =220Hz
Velocity or speed =440m/s
Velocity =Frequency *wavelength
Wavelength =Frequency/ Velocity

= 220/440

= 1/2
= 2m


​

Answer 1

Answer:

Ans Given,

Ans Given,Frequency =220Hz

Ans Given,Frequency =220HzVelocity or speed =440m/s

Ans Given,Frequency =220HzVelocity or speed =440m/sVelocity =Frequency *wavelength

Ans Given,Frequency =220HzVelocity or speed =440m/sVelocity =Frequency *wavelengthWavelength =Frequency/ Velocity

Ans Given,Frequency =220HzVelocity or speed =440m/sVelocity =Frequency *wavelengthWavelength =Frequency/ Velocity= 220/440

Ans Given,Frequency =220HzVelocity or speed =440m/sVelocity =Frequency *wavelengthWavelength =Frequency/ Velocity= 220/440= 1/2

Ans Given,Frequency =220HzVelocity or speed =440m/sVelocity =Frequency *wavelengthWavelength =Frequency/ Velocity= 220/440= 1/2= 2m

Answer 2

Answer:

Ans Given,

Ans Given,Frequency =220Hz

Ans Given,Frequency =220HzVelocity or speed =440m/s

Ans Given,Frequency =220HzVelocity or speed =440m/sVelocity =Frequency *wavelength

Ans Given,Frequency =220HzVelocity or speed =440m/sVelocity =Frequency *wavelengthWavelength =Frequency/ Velocity

Ans Given,Frequency =220HzVelocity or speed =440m/sVelocity =Frequency *wavelengthWavelength =Frequency/ Velocity= 220/440
