Oscillations - Result Question 62
68. Resonance is an example of
(a) tuning fork
(c) free vibration
(b) forced vibration
(d) damped vibration
Show Answer
Solution:
- (b) We know that if frequency of an external forced oscillation is equal to the natural frequency of the body, then amplitude of the forced oscillation of the body becomes very large. This phenomenon is known as resonant vibration. Therefore, resonance is an example of forced vibration.
