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 the wavelength of electromagnetic waves as you move from radio waves to gamma rays?

Back

The wavelength gets shorter.

Front

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

Back

As the wavelength increases, the frequency decreases, and vice versa.

Front

What type of electromagnetic wave has the highest frequency?

Back

Gamma rays have the highest frequency.

Front

What type of electromagnetic wave has the lowest frequency?

Back

Radio waves have the lowest frequency.

Front

How does the energy of electromagnetic waves relate to their frequency?

Back

As the frequency of an electromagnetic wave increases, the energy of the wave also increases.

Front

What is the frequency of a wave with a large wavelength?

Back

A wave with a large wavelength will have a low frequency.

Front

Do electromagnetic waves require a medium to travel?

Back

No, unlike mechanical waves, electromagnetic waves do not need a medium.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Electromagnetic waves travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second.

Front

What is visible light?

Back

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