Science 8: U4A Waves Test Review

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through.

Front

How do particles move in a longitudinal wave?

Back

In a longitudinal wave, particles move back and forth in the same direction as the wave.

Front

What is the relationship between crest and amplitude?

Back

The amplitude of a wave is measured as the distance from the crest (or trough) to the rest position.

Front

What does a wave carry?

Back

A wave carries energy.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium (solid, liquid, or gas) to travel through, while electromagnetic waves can travel through a vacuum.

Front

What is wavelength?

Back

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

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is a medium in the context of waves?

Back

A medium is the substance through which a wave travels, such as air, water, or solid materials.
