Class 11PhysicsOscillationsDifferent types of oscillations (Free, Damped, Forced Oscillation and Resonance)
MediumThe amplitude of vibration of a particle is given by $a_m = \frac{a_0}{a\omega^2 - b\omega + c}$,where $a_0, a, b,$ and $c$ are positive constants. The condition for a single resonant frequency is:
- A$b^2 = 4ac$
- B$b^2 > 4ac$
- C$b^2 = 5ac$
- D$b^2 = 7ac$
