The frequency (f) is determined by the speed of light (c) divided by the wavelength of the light (l), or f = c / l, where f is in cycles per second or Hertz (Hz), c is in meters per second, and l is in meters. So:

1.  f = (3.00...

The frequency (f) is determined by the speed of light (c) divided by the wavelength of the light (l), or f = c / l, where f is in cycles per second or Hertz (Hz), c is in meters per second, and l is in meters. So:

1.  f = (3.00 * 10^8 m/s) / (5.2 * 10^-7 m)

2.  f = (.577 * 10^15  1/sec) =

3.  f = 5.77 * 10^14  Hz.
