A sound wave has a frequency 1000 Hz and speed `330 m s^(-1)`. How long will it take to move through 1 km?

Text Solution

Verified by Experts

The correct Answer is:
3
Distance travelled ` = 1000m`
Speed of sound ` 330 ms^(-1)`
Time taken by the wave to move through 1 km
` = ("distance")/("speed") = (1000m)/(330 ms^(-1)) = 3.03 = 3s`
