Electromagnetic Spectrum

Front

What happens to the energy of waves as the wavelength gets shorter?

Back

The energy of waves increases.

Front

What is the height of a wave from its resting point called?

Back

Amplitude.

Front

What effect does increasing the amplitude of a wave have on its energy?

Back

It increases the wave's energy.

Front

Which type of waves are used to send signals, including WiFi and text messages?

Back

Radio waves.

Front

What type of waves make water molecules vibrate and warm up?

Back

Microwaves.

Front

What is the electromagnetic spectrum?

Back

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

Front

What is wavelength?

Back

The distance between two consecutive peaks or troughs in a wave.

Front

What is frequency in relation to waves?

Back

The number of waves that pass a point in one second.

Front

How are frequency and wavelength related?

Back

As frequency increases, wavelength decreases.

Front

What are gamma rays?

Back

High-energy electromagnetic waves with very short wavelengths.
