Question

A sound box emits a sound of wavelength 1.7m.The speed of sound in air is 340m/s.Will the sound be heard by a man? (Yes is the answer)show steps​

Answer 1

Answer:

yes of course

Explanation:

speed is equal to wavelength ×frequency

here frequency=200Hz ( speed/ wavelength) and human beings can hear sound upto 20000Hz from 20 Hz

Answer 2

OUR AUDIBLE RANGE IS FROM 20Hz to 20KHz

$f = \frac{v}{wavelength} \\ f = \frac{3400}{17} \\ f = 200hz$

AS THE FREQUENCY IS IN AUDIBLE RANGE THE SOUND WILL BE HEARD BY THE MAN
