Best ResponseYou've already chosen the best response.0E=ch/Wavelength In other words, Energy (in Joules) =speed of light (2.998x10^8 m/s) x Planck's constant (6.626 x 10^34) / wavelength in meters

Best ResponseYou've already chosen the best response.0So you just need to convert 12.4 MeV into Joules and plug it in to the equation
