If amplitude of a wave is represented by...

If amplitude of a wave is represented by `A=(c )/(a+b-c)`. Then the resonance will occur when.

A

`b=-c//2`

B

`b=0` and `a=c`

C

`b=(-a)/(2)`

D

none

Text Solution

Verified by Experts

The correct Answer is:
B
For resonance,t he amplitude should be infinitely large. The combination `(b=0` and `a=c`) best satisfies this condition.
