The Speed of Light in a vacuum is related to the wavelength and frequency of a light particle.
Speed of Light
Speed of Light Example 1
Even the music we listen to deals with how energy travels to get to our car radio. If an FM Radio station broadcasts its music at 97.7 MHz find the wavelength in angstroms of the radio waves. One angstrom is equal to 10-10 m.
The distance between the earth and the sun is 1.496 x 1017 μm. How long (in mins) will it take for light to go from the sun to earth?
