Unit 2.5 EM Review

Front

What is the Greenhouse Effect?

Back

The Greenhouse Effect is the process by which certain gases in the Earth's atmosphere trap heat from absorbed radiation, warming the atmosphere.

Front

Which wave has the greatest wavelength in a diagram?

Back

Wave 3 has the greatest wavelength.

Front

What activity contributes the most to global carbon emissions?

Back

Burning fossil fuels contributes the most to global carbon emissions.

Front

What is the term for the distance between points C & E in a wave?

Back

Amplitude is the term used to identify the distance between points C & E.

Front

Do all types of electromagnetic radiation travel at the same speed?

Back

True, all types of electromagnetic radiation travel at the same speed but differ in wavelength.

Front

What is electromagnetic radiation?

Back

Electromagnetic radiation is energy that travels through space at the speed of light in the form of waves.

Front

Define wavelength in the context of waves.

Back

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

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What are the main types of electromagnetic waves?

Back

The main types of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
