Question

A sound wave has a frequency of 2 KHz and wavelength 17 cm. How long it will take to travel 2 km?

Answer 1

Hey!

_____________________

Frequency = 2 kHz
v= 2kHz

k=1000
v= 2000 Hz

Wavelength = 17 cm
Wavelength = 0.17 m

Speed = Wavelength × Frequency
V= 0.17×2000
V= 340 m/s

Time taken by wave to travel distance of 2km (2000m) =

v= d/t
t= d/v
t= 2000/340
t=5.8 s

Hence, the sound wave will take 5.8 seconds to travel distance of 2km
