Electromagnetic Spectrum

Front

What are microwaves used for?

Back

Microwaves are used in ovens and cell phone communications.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

How do electromagnetic waves differ from other types of waves?

Back

Electromagnetic waves can travel through empty space.

Front

What happens to frequency as wavelength decreases?

Back

As the wavelength decreases, the frequency increases.

Front

Which type of electromagnetic wave has the shortest wavelength?

Back

Gamma Rays have the shortest wavelength and the highest frequency/most energy.

Front

Define the electromagnetic spectrum.

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What are infrared rays?

Back

Infrared rays are electromagnetic waves with wavelengths longer than visible light but shorter than microwaves.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

Electromagnetic waves travel at the speed of light, approximately 299,792 kilometers per second.

Front

What are ultraviolet rays?

Back

Ultraviolet rays are electromagnetic waves with wavelengths shorter than visible light but longer than X-rays.

Front

What is the main use of radio waves?

Back

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