Describe in brief, with the aid of a labelled diagram, an experiment to demonstrate that a material medium is necessary fur the propagation of sound.
Answer · 1 vote
Following is an experiment that demonstrates that a material medium is required for the propagation of sound:Suspend an electric bell in a bell jar, which is connected to a vaccum pump as observed in the figure.The circuit of the electric bell is completed. when the key is pressed.The hammer of the electric bell is observed to strike the gong constantly. and the sound of the bell is heard.Air is eventually withdrawn from the jar by starting the vaccum, keeping the key pressed still.Note that the loudness of sound keeps declining as the air is taken out from the bell jar, no sound is heard finally when the jar is completely void of air.The hammer of electric bell is still seen striking the gong constantly indicating that the gong is still vibrating, generating sound. but is not heard. Explanation - When the hammer hits the gong, sound is produced due to vibration of the gong that travels through the air to the wall of the jar.It causes the walls to vibrate due to which the air outside t…

Question
Explain the experiment with neat diagram to prove the following : Sound needs material medium for propagation
Answer · 1 vote
Bell jar experiment can prove that sound needs material medium for its propagation. Construction A bell jarA vacuum pump connected to the jar through a tubeAn electric bell inside the jar and is connected to the electric supply through the lid of the bell jar Working Initially the vacuum pump is 'OFF' so that air is present inside the jar. Now, if electric supply is switched on, the electric bell will start ringing and this ringing can be heard outside the bell jar.Now, switch on the vacuum pump such that it starts sucking the air inside the jar. It will be observed that, with the decrease in quantity of air inside the jar, the level of ringing sound heard outside also decreases. If the pump is used for sufficiently long period, then the quantity of air inside the jar will be so low that the ringing sound outside it will not be audible. This proves that sound requires medium for its propagation.

_____OBJECT REQUIRED____________________ GLASS JARELECTRONIC BELLVACCUM PUMPSWITHCHTHEN,______PROCEDURE_____________________AN ELECTRIC BELL IS TAKEN INSIDE AN AIRTIGHT GLASS JAR.IT IS SUSPENDED INSDE THE GLASS JAR.THE JAR IS CONNECTED TO A VACCUM PUMP.THE SWITCH IS ON AND AIR IS STARTED TO BE PUMPED OUT.THEN,_______OBSERVATION_______________________AT FIRST WE CAN HEAR THE RINGING SOUND OF BELL CLEARY. AS SOON AIR IS PUMPED OUT, THE SOUND OF THE BELL STARTS TO BECOME FEEBLE. AFTER THE AIR IS COMPLETELY VACATED OUT, NO SOUND IS HEARD.____________AFTER THIS EXPERIMENT THE CONCLUSION COMES, AS VACCUM IS CREATED IN THE JAR, NO SOUND IS HEARD. THIS MEANS SOUND ALWAYS NEEDS A MEDIUM TO TRAVEL.___________
