Waves & Sound

Front

What happens to a small object placed on a speaker when loud music is played?

Back

The object may move due to the vibrations of the sound.

Front

Why do sound waves travel fastest through solids?

Back

In solids, the atoms (particles) are closest together, allowing vibrations to travel rapidly from one to another.

Front

What determines the pitch of a sound produced by a musical instrument?

Back

The frequency of the vibrations determines the pitch.

Front

What is the term for the lowest point on a wave?

Back

The lowest point on a wave is called the trough.

Front

What type of wave produces a high pitch sound?

Back

A high frequency wave produces a high pitch sound.

Front

Define sound waves.

Back

Sound waves are vibrations that travel through a medium (solid, liquid, or gas) and can be heard when they reach a person's or animal's ear.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency corresponds to a higher pitch, while lower frequency corresponds to a lower pitch.

Front

What is a wave's amplitude?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the particle displacement is parallel to the direction of wave propagation, while in transverse waves, the particle displacement is perpendicular to the direction of wave propagation.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.
