Answer:
The first possible value of d is 0.85 m
The second possible value of d is 2.55 m
The third possible value of d is 4.25 m
Explanation:
Given that,
Distance =d
Frequency of sound wave= 200 Hz
We need to calculate the wavelength
Using formula of wavelength
Put the value into the formula
The separation between the speakers in the destructive interference is
The equation for destructive interference
The loudspeakers are in phase
So,
The equation for destructive interference is
....(I)
Here, m = 0,1,2,3.....
We need to calculate the first possible value of d
For, m = 0
Put the value in the equation (I)
We need to calculate the second possible value of d
For, m = 1
Put the value in the equation (I)
We need to calculate the third possible value of d
For, m = 1
Put the value in the equation (I)
Hence, The first possible value of d is 0.85 m
The second possible value of d is 2.55 m
The third possible value of d is 4.25 m
