What is the electromagnetic spectrum?

Back

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

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz).

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, usually measured in meters.

Front

How are frequency and wavelength related?

Back

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

Front

What type of electromagnetic radiation has the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

What type of electromagnetic radiation has the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

Which type of electromagnetic radiation has higher energy: ultraviolet rays or visible light?

Back

Ultraviolet rays have higher energy than visible light.

Front

What happens to the energy of waves as the wavelength decreases?

Back

The energy of waves increases as the wavelength gets shorter.

Front

What is the order of the electromagnetic spectrum from longest to shortest wavelength?

Back

Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays.

Front

Which has more energy: infrared waves or radio waves?

Back

Infrared waves have more energy than radio waves.
