Question

A sound wave has a frequency of 1k Hz and wavelength 25cm to travel 2.2Km it takes 2.2 km it takes
​

Answer 1

Answer:

88 seconds

Explanation:

It is given that,

Frequency of the sound wave, f = 1 kHz = 1000 Hz

Wavelength,

Distance covered, d = 2.2 km = 2200 m

The speed of sound wave in terms of frequency and the wavelength is given by :

v = 250 m/s

The speed of sound is also defined as the total distance covered divided by total time taken.

t = 8.8 seconds

So, the time taken by the sound wave is 8.8 seconds. Hence, this is the required solution.
