When two waves of almost equal frequencies n1 and n2 are produced simultaneously, then the time interval between successive maxima is –

A

1n1−n2\frac{1}{n_{1} - n_{2}}

B

1n1−1n2\frac{1}{n_{1}} - \frac{1}{n_{2}}

C

1n1+1n2\frac{1}{n_{1}} + \frac{1}{n_{2}}

D

1n1+n2\frac{1}{n_{1} + n_{2}}

Answer

1n1−n2\frac{1}{n_{1} - n_{2}}

Explanation

Solution

T = 1n1−n2\frac{1}{n_{1} - n_{2}}
