Electromagnetic Waves Practice

Electromagnetic waves vary in

• the speed they travel in a vacuum

• wavelength and frequency

• the way they reflect

• the orientation of their electric and magnetic fields

The full range of frequencies of electromagnetic radiation is called

• visible light

• the electromagnetic spectrum

• radio waves

• invisible radiation
