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 f a=c

C

b=-a/2

D

none

Text Solution

Verified by Experts

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