Front

What type of electromagnetic waves have the longest wavelengths and lowest frequencies?

Back

Radio waves.

Front

What happens to the size of atoms as you move across the periodic table?

Back

Atoms tend to get smaller because they have more protons.

Front

What is the relationship between wavelength, frequency, and energy in waves?

Back

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

Front

How does the energy level change from gamma ray to radio wave?

Back

The energy level decreases.

Front

In visible light, which color has the longest wavelength?

Back

Red.

Front

What is the electromagnetic spectrum?

Back

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

Front

What is the frequency of a wave?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What are microwaves used for?

Back

Microwaves are used for cooking food and in communication technologies.

Front

What is the significance of the visible spectrum?

Back
