The equation for photon energy, , is

where = 6.626×10−34 (Planck's constant) and = 3.00×108 (the speed of light).

What is the wavelength, , of a photon that has an energy of = 3.99×10−19 ?

How do go about solving this? I multipled the constant w/ the speed of light and divided it by the proton energy but its not correct

I've written this more than once but I'll try again. We need for you to show your work. Although it appears your method is right, you may not have substituted, multiplied, or divided correctly. Include the answer you obtained from your work.
