a-light-wave-has-a-frequency-of-4-70×10-14-hz-what-are-its-wavelength-and-color

I have the formulas that I am expected to solve this with (speed of light=wavelength + frequency, energy=Planck’s constant x frequency, speed of light=3.0×10^8 m/s, im=1×10^9 nm), but I do not know how to apply them to solve the problem.
