2.3 Electromagnetic Spectrum Flashcard

Front

This is measured in Hertz (Hz) and records how many times a wave oscillates in a second.

Back

Frequency

Front

This is a broad range of radiation that carries energy in the form of waves.

Back

Electromagnetic Spectrum

Front

When two different variables do the opposite thing

Back

Inverse relationship

Front

When two variables do the same thing (increase or decrease together)

Back

Direct relationship

Front

Which two variables of the electromagnetic spectrum have a direct relationship? (there may be more than one correct answer)

Back

Energy and frequency

Front

As wavelength increases, frequency __________ and energy ________.

Back

Decreases, decreases

Front

As the wavelength of a wave gets longer, what is also true?

Back

Frequency of the wave will decrease

Front

Based on the attached diagram, which type of electromagnetic radiation has the LOWEST energy? Options: microwave, ultraviolet, infrared, x-rays

Back

microwave

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

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.
