Question

Beats are produced by frequencies $v subscript 1 end subscript a n d v subscript 2 end subscript left parenthesis v subscript 1 end subscript greater than subscript 2 end subscript right parenthesis$ . The duration of time between two successive maximum or minima is equal to

$\frac{1}{v_{1} + v_{2}}$
$\frac{2}{v_{1} - v_{2}}$
$\frac{2}{v_{1} + v_{2}}$
$\frac{1}{v_{1} - v_{2}}$

The correct answer is: $fraction numerator 1 over denominator v subscript 1 end subscript minus v subscript 2 end subscript end fraction$

The time-interval between two successive beats
$T equals fraction numerator 1 over denominator b e a t blank f r e a q u e n c y end fraction equals fraction numerator 1 over denominator v subscript 1 end subscript minus v subscript 2 end subscript end fraction$
