Waves & Visible Light Review

Front

What is amplitude?

Back

The amplitude is the maximum distance that a wave moves from its rest position. It is a measure of the energy of the wave.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave. It determines the color of visible light.

Front

How does low energy affect frequency?

Back

Low energy results in low frequency. This means that waves with less energy have fewer cycles per second.

Front

What do all the colors of the rainbow combine to create?

Back

All the colors of the rainbow combine to create white light.

Front

What part of the electromagnetic spectrum can humans see?

Back

The only part of the electromagnetic spectrum that humans can see is known as visible light.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement of the wave from its rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the minimum displacement of the wave from its rest position.

Front

What is the relationship between energy and wavelength?

Back

Higher energy waves have shorter wavelengths, while lower energy waves have longer wavelengths.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 300,000 kilometers per second).

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, infrared, ultraviolet, X-rays, and radio waves.
