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.
