Question

three sound waves of equal amplitudes have frequencies n -1 n n + 1 day superimposed to give me the number of Beats produced per second will be​

Answer 1

beat frequency=n+1-(n-1)

=2

hope it helps

Answer 2

The number of beats produced per second will be 2 - n.

Explanation:

Beat frequency is defined as:

• The difference between the values of wave frequencies is called as beat frequency.
• The formula for the beat frequency is fb = f2 - f1
• Where f1 and f2 are the frequency of two waves.

Now

fb = f2 - f1

fb = (n + 1) - n- (n - 1)

fb = (n + 1 - n - n +1 )

fb = 2 - n

Thus the number of beats produced per second will be 2 - n.

Where n = frequency.
