Electromagnetic Radiation Wave Properties

• view radiant energy as propagating through space
  as vibrating electric and magnetic fields
  perpendicular to one another.
• velocity c
• 3.00 x 108 m/sec
• (speed of light)
• wavelength ????
• ??distance between peaks
• frequency ??????peaks/sec
• cps Hz sec-1
• amplitude height of wave

points where amplitude is zero node distance
between nodes ??/2 electromagnetic radiation
requires no medium
