Front

What type of wave is an electromagnetic (EM) wave?

Back

An electromagnetic wave is a transverse wave.

Front

Which electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength.

Front

What type of waves can be used to treat cancer?

Back

Gamma waves can be used to treat cancer.

Front

If the wavelength of an electromagnetic wave is longer, what happens to the energy?

Back

The energy is lower.

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 the speed of light).

Front

What is the electromagnetic spectrum?

Back

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

Front

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

Back

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

Front

What are microwaves used for?

Back

Microwaves are commonly used for cooking food and in communication technologies.

Front

What is the main characteristic of transverse waves?

Back

In transverse waves, the oscillation is perpendicular to the direction of wave travel.
