Does the presence of a sound box affect the duration of a tuning fork's sound?

AI Thread Summary
The presence of a sound box affects the duration of a tuning fork's sound by facilitating quicker energy transfer to the air, resulting in a shorter sound duration compared to the tuning fork alone. This occurs because the sound box dampens the vibrations of the tuning fork while also increasing the contact area with air, enhancing energy transfer. The discussion clarifies that both resonance and damping involve energy transfer, but the outcome differs based on how the energy is dissipated or transmitted. Ultimately, the sound box acts as a resonator that accelerates the loss of sound energy. Understanding this relationship is crucial for grasping concepts of resonance and damping in sound production.

Homework Statement


I was doing a question about resonance of sound box connecting to a tuning fork. It asks why the sound lasts for a shorter time with sound box than if the tuning fork is struck identically without the sound box.

Homework Equations

The Attempt at a Solution


Is it because the sound box dampens the vibration of tuning fork, or because due to larger contact area of box with air the box transfers vibrational energy at higher rate to air, or these two reasons are actually the same thing? So does it mean that resonator will always dampen the driving oscillator? I'm quite confused between the idea of energy transfer in resonance and damping. Thanks in advance:)

You are right that, to the energy source, there is no distinction between resonance and damping. Either way, it is a transfer of energy from the energy source to whatever is in contact with it. The difference arises after that, being a matter of whether the energy is merely dissipated within the contacting matter (damping) or transferred on.

Thanks for replying!
So the reason for shorter sound note is due to resonance? as the energy is transferred on from sound box to air as sound energy more quickly than the tuning fork alone?

Yes.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
