The energy difference between ground state of an atom and its excited state is `3xx10^(-19)J`. What is the wavelength of photom required for this radiation ?

If the energy difference between the ground state of an atom and in excited state is 4.4xx10^(-14)J , the wavelength of photon required to produce the transition is:
