Light and Sound Waves Review

The diagram represents the movement of sound from music playing through a speaker to a person’s ear. Which statement best explains which type of energy shown needs a medium through which to travel?

• Sound needs to travel through a medium because the energy is produced by a speaker

• Light needs to travel through a medium because it involves the movement of light rays

• Sound needs to travel through a medium because it involves the movement of particles

• Light needs to travel through a medium because the energy is moved in two directions

A student is investigating the transmission of sound waves and light waves through different mediums. The student tests sound wave and light wave transmission within a glass jar with air, without air, and with water. Select the answer that shows the mediums that will transmit sound waves and light waves.

• Sound: 1 &3. Light. 4,5,& 6

• Sound: 1,2 &3. Light. 4,5,& 6

• Sound: 1 &3. Light. 5,& 6

• Sound: 1, 2 &3. Light. 5,& 6

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?

• Sound waves are transverse waves.

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

• Sound waves do not transmit through material mediums.

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