Bell Resonance in Air vs. in Water

[Bell_Hunter]

Hi,

I am a noob and have a question with respect to resonance.

A bell hanging of a string been in Air, when struck, has resonance peak(s) in the audible and possibly ultra sound spectrum.

My questions is, if this very same bell would be hanging of a string and fully submerged in water, what would happen ?

Would the water dampen the resonance ?

Would the resonance peak(s) frequency change ?

Whats determine factor for resonance, speed of sound in the bronze material, speed of sound in air or speed of sound in water ?


Thanks for pointers

.The answer to your questions depends on the type of bell you are referring to. Generally, when a bell is submerged in water, the resonance will be dampened due to the fact that water has a much higher density than air. This means that the density of the medium affects the speed of sound and thus the resonant frequency of the bell. The speed of sound in bronze material is not a determining factor for resonance. Rather, the speed of sound in air and water are the factors that will affect the resonance peak frequency.

Hello there,

That's a great question! The concept of resonance can be a bit tricky to understand, so let me break it down for you in the context of your scenario.

Resonance occurs when an object is vibrating at its natural frequency, causing it to produce a loud and clear sound. In the case of a bell, the natural frequency is determined by the size, shape, and material of the bell. When the bell is struck, it vibrates at this natural frequency, producing a clear and sustained sound.

Now, let's consider the difference between air and water. In air, sound travels at a speed of approximately 343 meters per second, while in water, sound travels at a speed of approximately 1480 meters per second. This means that the speed of sound in water is much faster than in air.

So, what would happen if the bell was submerged in water? The first thing to note is that the bell would still produce a sound, but it would be much quieter. This is because water is denser than air, so it would absorb some of the sound energy produced by the bell. This is why when you are underwater, you can hear sounds, but they are muffled and not as clear as they are in air.

In terms of resonance, the speed of sound in the material of the bell is the determining factor. This means that the resonance peak(s) frequency would not change, even when the bell is submerged in water. However, the sound produced by the bell would be different due to the change in medium.

Overall, the main difference between resonance in air and water is the strength and clarity of the sound produced. In water, the sound would be dampened due to the denser medium, but the resonance frequency would remain the same. I hope this helps to answer your question.
