Resonance

When a body is vibrating under the influence of an external agency, with the frequency of external source then these are called resonant vibrations.

Forced and resonant vibrations are the same.

What are the difference between forced and resonant vibrations?

Draw and explain the amplitude-frequency graph of an object in resonance.

The amplitude will be high at a specific point in the amplitude-frequency graph if an object is forced to vibrate at its natural frequency.

What is the nature of the graph if an object is forced to vibrate at its natural frequency?

Mention the devices used in the experiment to show resonance with tuning forks.

Explain resonance with the help of a tuning fork.

Out of the following, select the one's which has resonance.

Group of soldiers marching on the bridge are often asked to break their steps because of _____.

Group of soldiers marching on the bridge are often asked to break their steps because of resonance.

"Resonance occurs when the natural frequency of a wave matches the frequency of the next wave". Give some examples of resonance.. 

Mention some examples of resonance.

Tabulate the differences between the forced and resonant vibrations.

 For forced vibrations, the amplitude of vibration is small whereas for resonant vibration, the amplitude of vibration will be large.

Explain the difference between forced and resonant vibration?

What is the relation between intensity of sound and its amplitude?

What do you mean by intensity of a sound wave?

In a parallel LCR circuit, the current at resonance will be

You are given four sound sources with frequencies $288 \mathrm{Hz}$, $314 \mathrm{Hz}$, $333 \mathrm{Hz}$ and $512 \mathrm{Hz}$. A tuning fork of frequency $256 \mathrm{Hz}$ will resonate with frequency of _____ $\mathrm{Hz}$.
