Question

a vibrating object has a time period of 0.05 seconds. will the sound be detected by the human ear or not? give reason​

Answer 1

Answer:

To get the sound heard by human ears, it must hold a frequency above 20 hz.

Here, time period = .06 seconds = 6/100 seconds.  

Frequency = Reciprocal of time period.

The time period of 0.06 seconds gives us as frequency of (100/6) = 16.67 hz, which is too low to be heard by human ears.

Thus this particular detected sound will not at all be heard by human bein

Answer 2

Answer:

Yes, the sound can be detected by the human ear because The time period of 0.05 seconds gives us as frequency of (100/5) = 20 hz, which will be audible to human ears.
