Since the color is oranfe and we need to find frequency the first thing that we should do is to divide the speed of light by \(2.998 * 10**8\) m per sec. of wavelength which was given in that way \(6.2 * 10**-7\). The next thing you should do is do the division and in a result you will have \(4.835 * 10**14 cycles per second\)
