Electromagnetic Spectrum

Front

What are gamma rays?

Back

Gamma rays are electromagnetic waves with the highest frequencies and the shortest wavelengths in the electromagnetic spectrum.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the complete range of electromagnetic waves arranged in order of increasing frequency.

Front

How much of the electromagnetic spectrum is visible to the human eye?

Back

Only a small part of the electromagnetic spectrum is visible to the human eye.

Front

What is ultraviolet (UV) radiation?

Back

Ultraviolet radiation can carry more energy than visible light and has shorter wavelengths and higher frequencies than visible light.

Front

Which electromagnetic waves have wavelengths longer than microwaves?

Back

Radio waves have wavelengths longer than microwaves.

Front

What is the order of the electromagnetic spectrum from lowest to highest frequency?

Back

The order is: Radio waves, Microwaves, Infrared, Visible light, Ultraviolet, X-rays, Gamma rays.

Front

What is the frequency of visible light compared to infrared waves?

Back

Visible light has a higher frequency than infrared waves.

Front

What type of electromagnetic waves can be used for communication?

Back

Radio waves are commonly used for communication.

Front

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

Back

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

Front

What are X-rays used for?

Back

X-rays are used in medical imaging to view the inside of the body.
