A sound wave has frequency of 4 kHz and its wavelength is 35 cm. How much time will it take to travel a distance of 3 km?

A sound wave has a frequency of 4 kHz and wavelength 30 cm. How long will it take to travel 2.4 km ?

A sound wave has a frequency of 1 kHz and wavelength 50 cm. How long will it take to travel 1 km?

A sound wave having frequency of 300 Hz is travelling in an unknown medium. Its wavelength is not known. It travels a distance equal to 150 times its wavelength in time t. The value of t is :

The frequency (ƒ), wavelength (λ) and speed (v) of a sound wave are related as

A sound wave travelling at a speed of 330 m/s produces 20 crests and 20 troughs in 0.1 second. The wavelength (λ) of the sound wave is:
