Resonance in Waves starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Resonance in Waves.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11

Fill in the blank: In resonance, the amplitude of oscillation becomes ________ compared to non-resonant conditions.
Fill in the blank: The amplitude of a resonating system is maximum when the driving frequency is ________ to the natural frequency.
Fill in the blank: The sharpness of resonance is determined by the ________ of the system.
The natural frequency of a system is the frequency at which it ________ when not subjected to a continuous or repeated external force.
True or False: All systems with a natural frequency will always experience resonance if subjected to any external force.
True or False: In a lightly damped system, the resonance peak is sharper and the amplitude at resonance is higher.
True or False: Resonance can cause structural damage in buildings and bridges if not properly accounted for.
True or False: Resonance can only occur in mechanical systems, not in electrical or acoustic systems.
