I understand how to use the E=hf / E=hc/wavelength formula, but this question threw me off because they give you the energy in terms of keV instead of joules and I'm confused as to how they get the correct answer. (I got the question correct, but it was due to an educated guess that ive never seen a x10^- exponent value for frequency.)
