Question

A sound wave has a frequency of 3.5 kHz and wavelength 0.1 m.How long will it take to travel 700 m?​

Answer 1

Answer:

2 s

Explanation:

Wavelength=0.1m

Frequency=3.5kHz=3500Hz

Velocity(speed) =  f (Frequency) * λ(wavelength) = 3500*0.1=350m/s

Distance=700m

Speed=350m/s

t= Distance / Speed= 700/350 = 2s
