Question

Sound wave of wavelength 25cm , travels a distance of 1550m in 1

second . Find its frequency ? Can this sound be heard by human ear ?​

Answer 1

Explanation:

Speed of sound = distance travelled/time taken;

Speed = 1550/1

= 1550m/s

Now, frequency = speed / wavelength

= 1550/0.25

= 155000/25

= 6,200 Hz

Yes this sound can be heard by a human ear.

That's all.
