c=3.0 x 108m/s (the speed of light in a vacuum) This constant "c" is how fast electromagnetic radiation (light for all extensive purposes) travels. The other is "h", which called Planck's constant. h=6.626 x 10-34 J s. This comes from the work of Max Planck preformed in 1900 using blackbody radiation.
