Answer:
Hii,
Explanation:
Range=16.5m−16.5mm
According to question, Temperature is constant and other surroundings are constant (gas,pressure etc...).
⟹ Formula for Velocity of Sound remain same i.e., v=uλ , where v is the speed of sound, u is the frequency and λ is the wavelength of sound.
Velocity of Sound remains constant i.e., v=330m/s (# According to question given)
Range of Frequency(u) given, 20−20000 Hz
And, λ=v/u
⟹ Range of Wavelength(λ
R
) is, 330/20−330/20000≅16.5m−16.5mm
⟹ Range=16.5m−16.5mm
Hope this helps you..
