View Phys123_equation_sheetpdf from PHY 101 at City University of Seattle. C f where. The Wave Equation One of the most fundamental equations to all of Electromagnetics is the wave equation which shows that all waves travel at a single speed - the speed of light.
Its exact value is defined as 299 792 458 metres per second approximately 300 000 kms or 186 000 mis.
C 1e0m012 2998 X 108ms. C the speed of light 300000 kms or 30 x 10 8 ms the wavelength of light usually measured in meters or Angstroems 1 A 10-10 m f the frequency at which light waves pass by measured in units of per seconds 1s. The speed of light is close to 300000 kms 186300 miles per second. Another way of writing this is.
