Question

Two harmonic sound waves reach an overseveer simulatenouslt. the obsever hears the sound intensity rise and fall with a time of 0.2 between the maximmu intensity and the successing minimum intensity. What is the difference in frequency of the two sound waves?

Answer 1

`dF=2.5Hz`

Step-by-step explanation:

From the question we are told that:

Time
`T=0.2sec`

Generally the Period is given as

`T= 2 * 0.2 = 0.4`

Therefore difference in frequency dF

`dF=(1)/(T)`

`dF=(1)/(0.4)`

`dF=2.5Hz`
