Question

A student performs an experiment to study how sound waves are transmitted by placing a ringing buzzer inside a bell jar and sealing the jar. The student then connects the bell jar to a vacuum pump to remove the air from inside of the jar. The table shows the student’s observations before and after removing the air from the bell jar.

What can be concluded from the experiment?

A. Sound waves are transverse waves.

B. Sound waves do not transmit through material mediums.

C. Sound waves do not carry energy when they are transmitted.

D. Sound waves transfer energy through the vibration of particles in mediums.

Answer 1

D. Sound waves transfer energy through the vibration of particles in mediums.

Step-by-step explanation:

It can be concluded from the experiment that sound waves will only propagate through vibration of particles in mediums.

The particles of the medium is the air.

• This type of wave is called a mechanical wave.
• A mechanical wave is one that requires material medium for their propagation.

Option A ; Sound waves are transverse waves; while this might be true or not, we cannot ascertain that through this experiment described.

Option B: this negates the conclusion that should be drawn from the experiment.

Option C: we cannot draw this sort of conclusion from such an experiment as this.

Therefore, the right choice is that, sound waves transfer energy through the vibration of particles in mediums.
