Two waves are approaching each other with a velocity of `20m//s` and frequency `n`. The distance between two consecutive nodes is

A

`(20)/(n)`

B

`(10)/(n)`

C

`(5)/(n)`

D

`(n)/(10)`

Text Solution

Verified by Experts

The correct Answer is:
B
Distance between the consecutive node `=(lamda)/(2)`
But `lamda=(v)/(n)=(20)/(n)` so `(lamda)/(2)=(10)/(n)`
