Unit 3 Waves and Information Transfer

Front

What is amplitude in a wave?

Back

Amplitude is half of the distance from the crest to the trough of the wave.

Front

What does low amplitude indicate about energy?

Back

Low amplitude has low energy.

Front

What is a trough in a wave?

Back

The trough is the bottom part of a wave.

Front

What does the color we see represent in terms of light?

Back

The color we see is being reflected off of the objects.

Front

How do water waves move objects?

Back

Water waves move objects up and down.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

How does wavelength relate to wave energy?

Back

Shorter wavelengths generally have higher energy.

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves carry more energy.

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy through matter or space.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.
