Question

Which of the following scenarios describes a condition in which resonance can occur?

A. Two tuning forks that vibrate at the same frequency are near each other. One tuning fork is struck with a mallet so that it vibrates.
B. Two tuning forks are struck simultaneously, one with a frequency of 659Hz and one with a frequency of 639 Hz, causing beats.
C. A tuning fork is over a column of air that is 9/2 the wavelength of the wave produced by the tuning fork.
D. An isolated tuning fork is struck with a mallet, causing it to vibrate strongly at 659 Hz.

Answer 1

Answer:

C. A tuning fork is over a column of air that is 9/2 the wavelength of the wave produced by the tuning fork.

Explanation:

As we know that the frequency in the air column is given by

$f = \frac{v}{\almbda}$

now we know that the length of air column is L then at the condition of resonance we have

$N\frac{\lambda}{2} = L$

so here at the condition of resonance the length will be integral multiple of half of the wavelength.

So here for N = 9 we have

$L = \frac{9}{2}\lambda$

so here correct answer will be

C. A tuning fork is over a column of air that is 9/2 the wavelength of the wave produced by the tuning fork.

Answer 2

Option C describes a condition in which resonance can occur. A tuning fork is over a column of air that is 9/2 the wavelength of the wave produced by the tuning fork.

What is resonance frequency?

Mechanical systems and charged particles all have a frequency that they vibrate at. This frequency is referred to as the resonance frequency or natural frequency.

When a light or sound wave impacts an item that is already vibrating at a specific frequency, and that frequency happens to match the resonant frequency of the thing being struck, you get resonance.

A tuning fork is over a column of air that is 9/2 the wavelength of the wave produced by the tuning fork.

Hence option C describes a condition in which resonance can occur.
