Electromagnetic Spectrum

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

What happens to frequency as wavelength increases?

Back

As the wavelength of an electromagnetic wave gets longer, the frequency gets lower.

Front

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

Back

Ultraviolet waves have a higher frequency than visible light.

Front

Which electromagnetic wave has the shortest wavelength?

Back

Gamma rays have the shortest wavelength and the highest frequency.

Front

What type of wave has the largest wavelength on the electromagnetic spectrum?

Back

Radio waves have the largest wavelength and the lowest frequency.

Front

Do all electromagnetic waves travel at the same speed in a vacuum?

Back

Yes, all electromagnetic waves travel at the same speed in a vacuum.

Front

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

Back

Higher frequency electromagnetic waves carry more energy.

Front

What type of electromagnetic radiation is used in remote controls?

Back

Infrared radiation is commonly used in remote controls.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from wavelengths of about 400 to 700 nanometers.
