Electromagnetic Spectrum Practice

Front

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.

Gamma Rays, X-rays, Ultraviolet, Visible Light, Infrared, Microwaves, Radio Waves.

Front

What is the only part of the electromagnetic spectrum that humans can see?

Back

Visible Light.

Front

What is wavelength?

Back

Wavelength is the distance between two crests or two troughs of a wave.

Front

Which type of electromagnetic wave has the longest wavelength?

Back

Radio Waves.

Front

What is frequency in the context of electromagnetic waves?

Back

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

Front

What type of electromagnetic wave has a higher frequency than visible light?

Back

Ultraviolet.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the shortest wavelength and highest energy.

Front

What is the significance of infrared waves?

Back

Infrared waves are used in various technologies, including remote controls and thermal imaging.
