What is the frequency of electromagnetic radiation that has a wavelength of 1.69 x 10^-8 meters?

Am I supposed to use the de Broglie wavelength formula?  If so, is the mass of an electron constant for all atoms?

When you know the wavelength, you can find the frequency from the speed of light, 3x10^8 m/s.
