Chapter 17: Electromagnetic Waves Review Game

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes different frequencies and wavelengths, from radio waves to gamma rays.

Front

How many different frequencies are in the electromagnetic spectrum?

Back

There are 7 different frequencies in the electromagnetic spectrum.

Front

What type of light has a wavelength shorter than ultraviolet waves?

Back

X-ray light has a shorter wavelength than ultraviolet waves.

Front

What are the uses of X-rays?

Back

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

Front

What part of a wave is the highest point called?

Back

The highest point of a wave is called the crest.

Front

What type of wave does an electromagnetic wave resemble?

Back

An electromagnetic wave closely resembles a transverse wave.

Front

What is the wavelength of a wave?

Back

The wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

Front

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

Back

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

Front

What are infrared waves used for?

Back

Infrared waves are commonly used in remote controls, thermal imaging, and night vision.
