What color corresponds to the longest wavelength in visible light?

Back

Red corresponds to the longest wavelength in visible light.

Front

What type of wave has particles that move perpendicular to the direction of wave travel?

Back

Transverse waves have particles that move perpendicular to the direction of wave travel.

Front

Which type of electromagnetic radiation has the shortest wavelength?

Back

Front

What color corresponds to a medium wavelength in visible light?

Back

Green corresponds to a medium wavelength in visible light.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What type of wave is a radio wave?

Back

Radio waves are a type of electromagnetic wave.
