For any wave, the product of the wavelength and frequency equals the speed of the wave. So you'll this formula: c = f*w, where c is the speed of light, f is the frequency, and w is the wavelength.
First, convert the given wavelength from nanometers to meters. Second, look up the speed of light in meters per second. Finally, solve the equation for the frequency, and plug in your values for c and w. You should expect to get a very large number for the frequency. The unit will be hertz.

Verified answer
divide the speed of the light: 3.0 x 10^8 m/s by the wavelength of the light: 5.15 x 10^-7 m.
the answer would be 5.83 x 10^14 Hz
