Question

On a hot summer day, a little mosquito produces a warning sound near your
ear by vibrating its wings at the rate of 3,000 wing beats per five seconds. State
the frequency, in hertz, of this sound. Is this sound odbiale give resonde​

Answer 1

Answer:

n=3000

t=50 sec

v=n/t

so

v=3000÷50

=== 60

Answer 2

Here Beats are the oscillations of the wings

No. of oscillations, n = 3000

Time taken , t = 5 s

Frequency of vibrating wings , v = n / t

=> v = 3000 / 5 = 600 Hertz = 600 Hz.

Audible range is between 20 Hz to 20000 Hz...

600 Hz of frequency lie within the above range , Therefore , this frequency is audible..
