Electromagnetic Spectrum Worksheet

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.

Front

Which type of electromagnetic wave has the longest wavelength?

Back

Radio Waves.

Front

What is the only section of the electromagnetic spectrum that is visible to the human eye?

Back

Visible Light.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are electric and magnetic fields (energy) that travel through empty space very quickly.

Front

How are wavelength and frequency related?

Back

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

Front

What type of electromagnetic wave has the highest energy?

Back

Gamma Rays.

Front

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

Back

Higher frequency waves have higher energy.

Front

Which electromagnetic wave has the lowest energy?

Back

Microwave.

Front

What is the wavelength range of visible light?

Back

Visible light has wavelengths approximately between 400 nm (violet) and 700 nm (red).

Front

What are infrared waves used for?

Back

Infrared waves are commonly used in remote controls, thermal imaging, and night vision.
