Waves, Sound, Heat, and Light

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (solid, liquid, or gas) by causing the particles of the medium to vibrate.

Front

What is rarefaction in a sound wave?

Back

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

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is the period of a wave?

Back

The period is the time it takes for one complete cycle of a wave to pass a given point.

Front

What is frequency in relation to waves?

Back

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

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that do not require a medium to travel through and can move through a vacuum.

Front

What is the relationship between frequency and period?

Back

Frequency and period are inversely related; as frequency increases, the period decreases, and vice versa.
