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

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

Best Answer

Sol. ||| We know that,

v = f × l (i)

Given,

Speed, v = 440 m/s

Frequency, f = 220 Hz

Wavelength l =?

Putting these values in (i), we get:

440 = 220 × l

l =  220/440

 = 2 m
