Why sound is produced when bell is struck with hammer?
Sound are produced by collition of molecules. When an object is beaten with bell. The molecule of metal bell moves and produces sound.
When the air in a bell jar containing a ringing bell is removed the sound decreases. why?
Sound cannot travel in a vacuum.
Experiment to show that sound cannot travel through a vacuum?
-> Suspend an electric bell in an airtight bell jar attached to a vacuum pump. -> Turn on the electric bell. -> Pump out all the air in the bell jar using the vacuum pump. -> The sound of the bell should get fainter as air is pumped out. -> Finally no sound can be heard even though the hammer can be seen hitting the bell
What did the bell in a vacuum tell scientists about sound?
THat sound requires matter to travel to be heard. Therefore a vacuum has no matter hence no sound can be heard
Experiment to demonstrate that sound need a material medium to propagate?
Take an electric bell and hang this bell inside an empty bell-jar fitted with a vacuum pump (as shown in the following figure). Initially, one can hear the sound of the ringing bell. Now, pump out some air from the bell-jar using the vacuum pump. It will be observed that the sound of the ringing bell decreases. If one keeps on pumping the air out of the bell-jar, then at one point, the glass-jar will be devoid of any air. At this moment, no sound can be heard from the ringing bell although one can see that the prong of the bell is still vibrating. When there is no air present inside, we can say that a vacuum is produced. Sound cannot travel through vacuum. This shows that sound needs a material medium for its propagation.
What can you hear when a bell rings in a vacuum?
No sound. Beacuse sound need air to travel..
Why cant you hear a bell inside of a vacuum jar?
Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.
What are the jobs in the bell jar experiment for the foam block and vacuum pump?
The vacuum pump stops the sound waves from coming out. Because there are no particles to pass on the sound in a vacuum, we see the clock vibrating, but do not hear anything at all.
How can you show that sound is a form of mechanical energy?
Sound can only travel through a medium (matter). Different materials allow sound to travel faster or slower. However, as an experiment put an electron bell in a bell jar. You hear it ring. Evacuate the bell jar of as much gas a possible ( a true vacuum is almost impossible to achieve in a Bell Jar), allow the bell to ring again. It will be much quieter, although the bell hammer will be vibrating at the same speed. By extrapolation, when all the gas is evacuated(vacuum) there will be no sound. So sound needs a medium to travel through.
What is an experiment to demonstrate that sound requires a medium to travel?
Making some sound (ringing a bell, dropping an object, etc.) inside a vacuum.
Can sound wave pass through in vacuum?
No - sound wave cannot pass through "vacuum". It was Robert Boyle, English scientist who proved in 1960 that sound waves need to pass through a medium to transmit sound. This can be tested as follows: Place a bell inside a chamber and slowly start evacuating air from the chamber. It can be seen that sound of the bell is slowly becoming softer, until there is absolutely no sound.
Can a bell make sound waves under water?
Yes
