What are microwaves used for?

Back

Microwaves are used in ovens for cooking food and in cell phone communications.

Front

Which electromagnetic waves have the highest frequencies?

Back

Gamma rays have the highest frequencies and the shortest wavelengths in the electromagnetic spectrum.

Front

What is the order of electromagnetic waves from longest wavelength to shortest wavelength?

Back

The order is: Radio, Microwave, Infrared, Visible Light, Ultraviolet, X-ray, Gamma.

Front

What section of the electromagnetic spectrum can we see?

Back

The only section of the electromagnetic spectrum that we can see is visible light.

Front

How does wavelength relate to frequency and energy?

Back

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

Front

What are radio waves used for?

Back

Radio waves are used for communication, including radio and television broadcasting.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, often associated with heat.

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.

Front

What are ultraviolet rays?

Back

Ultraviolet rays are electromagnetic waves with wavelengths shorter than visible light but longer than X-rays, known for their ability to cause sunburn.
