using the formula frequency =speed/wavelength
note there are scientific terms for these expressions, you'll have to read them up in/at your own time
frequency=3 x10^8/400x10^-9 = 7.5 x 10^14Hz
^means to the power of the number, the numbers used for the calculation, are the value for the speed of light and the 400nm converting to m respectively

c = lambda x nu
c is the speed of light 3.0 x 10^8 m/s
lambda is the wavelength
nu is the frequency
