• Electromagnetic radiation – a form of energy that displays characteristics of a wave as it moves through space

• Waves are characterized by wavelengths and frequencies– Wavelength ( λ ) – the distance
between the same points on two successive waves
• Units of meters (m)
– Frequency ( f ) – the number of wave cycles that are completed during a unit of time• Units of hertz, Hz, or inverse seconds,
s-1 or 1/s

• Speed of light ( c ) – the speed at which electromagnetic radiation travels– Speed of light is a constant
• Units of speed of light are meters per second
