Front

On the electromagnetic spectrum, radio waves are found on the end of the spectrum considered to possess a low amount of energy. Which statement most accurately describes the wavelength/frequency relationship present in radio waves?

Back

Radio waves possess low frequencies and large wavelengths.

Front

Which type of electromagnetic radiation has the LOWEST energy?

Back

Microwave

Front

Which two variables of the electromagnetic spectrum have a direct relationship?

Back

Energy and frequency.

Front

Why can ultraviolet rays cause sunburn but visible light from a light bulb does not damage skin?

Back

Ultraviolet rays have higher frequency than visible light rays and thus have more energy than light rays from a light bulb.

Front

What is the electromagnetic spectrum?

Back

The range of all types of electromagnetic radiation, ordered by wavelength or frequency.

Front

What is the relationship between frequency and energy in the electromagnetic spectrum?

Back

Higher frequency corresponds to higher energy.
