Chemistry Calculating Wavelength Help :)?

Calculate the wavelength, in nm, of electromagnetic radiation emitted by a hydrogen atom when its electron drops from energy level n = 8 to energy level n = 4. (Express your answer to 3 significant figures.)

Here is what I have so far in order to do this:

E= -2.18 x E-18 (1/4^2 - 1/3^2)

Anybody know how to do this? I really need some help!
