Sound Waves Quiz

What type of waves are sound waves?

• Electromagnetic waves

• Mechanical waves

• Heat waves

• Light waves

How do sound waves travel through a medium?

• Sound waves travel through a medium by creating a vacuum in front of them.

• Particles in the medium are displaced from their equilibrium position and then return to it, passing the energy of the wave along.

• Sound waves travel through a medium by changing the color of the medium.

• Sound waves travel through a medium by emitting light particles.

Explain the concept of frequency in sound waves.

• Frequency in sound waves is the speed of sound.

• Frequency in sound waves is measured in decibels.

• Frequency in sound waves is the amplitude of the wave.

• Frequency in sound waves is the number of cycles of a wave that occur in one second. It is measured in Hertz (Hz).

What is the speed of sound in air?

• 500 meters per second

• 700 meters per second

• 123 meters per second

• 343 meters per second

Can sound waves travel through a vacuum? Why or why not?

• No

• Sometimes

• Only on Tuesdays

• Yes

Describe how sound waves are produced.

• Sound waves are produced by gravitational force.

• Sound waves are produced by vibrations of an object.

• Sound waves are produced by light waves.

• Sound waves are produced by magnetic fields.

What is the relationship between wavelength and frequency in sound waves?

• Unrelated

• Direct

• Inverse

• Parallel

How does the amplitude of a sound wave affect its volume?

• Amplitude affects pitch, not volume.

• Higher amplitude results in lower volume.

• The amplitude of a sound wave directly affects its volume.

• The amplitude of a sound wave has no impact on its volume.

What is the unit of measurement for frequency?

• Hertz (Hz)

• Newton

• Volt

• Watt

Explain how sound waves can be reflected.

• Sound waves cause the surface to vibrate

• Sound waves pass through the surface without any change

• Sound waves are absorbed by the surface

• When sound waves hit a smooth and hard surface, they bounce off in a different direction.
