Question

Beats are produced by frequencies f1 and f2(f1 > f2). The duration of time between two successive maxima or minima is equal to (A)  (1/f1 +f2) (B)  (2/f1-f2) (C)  (2/f1 +f2) (D)  (1/f1-f2)

The time-interval between two successive beats T=(1/ text beat frequency )=(1/f1-f2)

Q. Beats are produced by frequencies $f_{1}$ and $f_{2} (f_{1} > f_{2})$ . The duration of time between two successive maxima or minima is equal to

$\frac{1}{f _{1} + f _{2}}$

$\frac{2}{f _{1} - f _{2}}$

$\frac{2}{f _{1} + f _{2}}$

$\frac{1}{f _{1} - f _{2}}$

The time-interval between two successive beats
$T = \frac{1}{beat frequency} = \frac{1}{f _{1} - f _{2}}$

Q. Beats are produced by frequencies f1​ and f2​(f1​>f2​). The duration of time between two successive maxima or minima is equal to

f1​+f2​1​

f1​−f2​2​

f1​+f2​2​

f1​−f2​1​
