Sound Waves Quiz

What is a sound wave?

• A sound wave is a type of wave that is created by light energy.

• A sound wave is a type of wave that is created by magnetic fields.

• A sound wave is a type of wave that is created by vibrating objects and travels through a medium such as air or water.

• A sound wave is a type of wave that is created by gravitational force.

What is the difference between frequency and wavelength of a sound wave?

• Frequency measures how often a sound wave repeats, while wavelength measures the distance between two consecutive points of the wave.

• Frequency measures the distance between two consecutive points of a sound wave, while wavelength measures how often the wave repeats.

• Frequency measures the speed of a sound wave, while wavelength measures the amplitude of the wave.

• Frequency measures the loudness of a sound wave, while wavelength measures the pitch of the wave.

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

• The amplitude of a sound wave has no effect on its loudness.

• The amplitude of a sound wave affects its duration, not its loudness.

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

• The amplitude of a sound wave affects its pitch, not its loudness.

What is reflection of sound?

• The reflection of sound is the phenomenon where sound waves bounce off a surface and change direction.

• The reflection of sound is the phenomenon where sound waves pass through a surface and change direction.

• The reflection of sound is the phenomenon where sound waves disappear after hitting a surface.

• The reflection of sound is the phenomenon where sound waves travel faster after bouncing off a surface.

What is refraction of sound?

• The change in direction or bending of sound waves as they pass from one medium to another with different densities.

• The reflection of sound waves as they pass through a medium with the same density.

• The absorption of sound waves by a medium with lower density.

• The amplification of sound waves as they pass through a medium with higher density.

How does the density of a medium affect the speed of sound?

• The speed of sound increases as the density of the medium increases.

• The density of the medium has no effect on the speed of sound.

• The speed of sound remains constant regardless of the density of the medium.

• The speed of sound decreases as the density of the medium increases.
