Beast are produced by frequencies `v_(1)` and `v_(2) (v_(1) gt v_(2))`. The duration of time between two sucessive maximum or minima is equal to

A

`1/(v_(1)+v_(2))`

B

`2/(v_(1)-v_(2))`

C

`2/(v_(1)+v_(2))`

D

`1/(v_(1)-v_(2))`

Text Solution

Verified by Experts

The correct Answer is:
D
The time-interval between two successive beats
`T=(1)/("Beat frequency")=1/(v_(1)-v_(2))`
