Waves and Sound

Front

What is the relationship between pitch and frequency?

Back

The pitch of a sound is most closely related to the frequency of the sound waves. Higher frequency results in a higher pitch.

Front

Define rarefaction in the context of waves.

Back

Rarefaction is the region in a longitudinal wave where the particles are spread apart, resulting in lower pressure.

Front

What does amplitude refer to in a wave?

Back

Amplitude refers to the maximum displacement of points on a wave from its rest position. It is related to the energy of the wave.

Front

What are transverse waves?

Back

Waves that have vibrations that move perpendicular to the direction of the wave's travel.

Front

What are mechanical waves?

Back

Waves that require a medium (solid, liquid, or gas) to travel through.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, particles move parallel to the direction of the wave, while in transverse waves, particles move perpendicular to the direction of the wave.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance traveled by a wave in a given amount of time, calculated as speed = wavelength × frequency.

Front

What is the principle of superposition?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual wave displacements.
