<strong>Electromagnetic</strong> Radiation is carried in the form of fluctuating electric and magnetic fields which are perpendicular to each other.
- Range of electromagnetic radiation from radio waves to gamma rays - Each type is defined by the specific wavelength and frequency - All travel at the same speed… the speed of light (186,00 miles/sec or 300,000 km/sec) - Wavelength x frequency= velocity
