Question

a sound has frequency 30000Hz express this terms in terms of angular frequency

Answer 1

Answer:

For a sound wave,

Speed = Wavelength x Frequency v = 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
