Theory

• The speed of electromagnetic waves is predicted
  from Maxwells equations to be
• for all types of electromagnetic radiation
  (light, radio waves, etc.) and in any frame of
  observation.

Our speed of light

• By using a Scientist program, we find a slope
  and, by doing simple calculation, find value for
  speed of light .
• Our speed of light
• c (2.832 0.035) 108 m/s without reckon in
  uncertainties for time,
• and
• c (2.861 0.042) 108 m/s with reckon in
  uncertainties for time.
• The table value for speed of light is 2.998
  108 m/s.
