On test 2 #4 a) the question says at the threshold level light is emitted with energy equal to 3.61x10^-22 kJ. Find the frequency of the emitted photon.

How do I find the frequency of the emitted photon? Is it just the normal E=hV? --> E/h = V ?

Convert kilojoules to joules. Use E/h = v. The answer should be 5.45 x 10^14 Hz.
