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
A mass-spring system has a natural frequency of 5 Hz. If it is driven by an external force at 5 Hz, what will happen to the amplitude of oscillation?
A pipe closed at one end has a fundamental frequency of 300 Hz. What is the frequency of its third harmonic?
A tuning fork of frequency 440 Hz is struck and held near a guitar string. The string begins to vibrate loudly. What phenomenon is being demonstrated?
A wine glass has a natural frequency of 600 Hz. If a sound wave of 600 Hz is produced nearby, what is likely to happen to the glass?
Calculate the natural frequency (in Hz) of a mass-spring system with mass 0.5 kg and spring constant 200 N/m. (Use f = (1/2π)√(k/m))
Describe how resonance is used in tuning a radio to a specific station.
Describe the difference between resonance and forced vibration.
Describe what happens to the amplitude of a driven oscillator as the driving frequency approaches the natural frequency.
Explain the effect of damping on resonance in a vibrating system.
Explain why a child on a swing experiences higher amplitudes when pushed at regular intervals matching the swing's natural frequency.
Explain why soldiers are often ordered to break step when crossing a bridge.
If a system has high damping, what happens to the resonance peak in its amplitude vs. frequency graph?
The Tacoma Narrows Bridge collapse in 1940 is an example of which physical phenomenon?
What is resonance in the context of waves and sound?
What is the term for the frequencies at which resonance occurs in a system?
