Can you at least try to use understandable English? What does "so the 14th jules" mean? But yes, E=hf, so you just multiply frequency by h to get energy. (I assume you mean energy and not energy level. Energy level is an entirely different concept.)

Sorry about that I meant to write TO the 14th joule, but thanks for the help I think I got it.
