The frequency of the sound
Answer to Problem 79GP
The frequency of sound is
Explanation of Solution
Given:
The audible range of the frequency ,
The sound is minimal at a distance,
Formula used:
Write the expression for frequency.
here
The difference in distance from the two sources must be an odd number of half wavelength for destructive interference.
Calculation:
For n=1 in equation (2):
Put the value from equation (3) in equation (1):
For n=3:
This is value is beyond the range.
Conclusion:
The frequency of sound is
