Question

Audio frequencies have a range 40hz to 30000hz
express this range in terms of time period
T and wave length Given velocity of Sound
on air = 3650 ms1

​

Answer 1

Answer:

85.7142857142 m

Explanation:

For a sound wave,

Speed = Wavelength x Frequencyv = λ x ν

Speed of sound in air = 350 m/s (Given)

(i) For, ν= 40 Hz

λ1= v/ν = 350/40 =8.705 m

(ii) For, ν= 30000 Hz

λ2= v/ν = 350/30000 = 85.7142857142 m
