Hi...
I need help with this problem

What is the wavelength (in nanometers) associated with a photon with energy equal to 1.4 x 10 -18 J ? thats 10 to the negative 18th

i tried using the formula delta E hv and worked backward with it but im not really getting anywhere thanks


Edited title for clarity. Mitch

E = hv = hc/wavelength
