how did you get the answer 67 to the question the neergy of the photon, to the nearest tenth place, is           x10-50J?

bobpursley · Answer

I have no idea what you are refering to, but the energy of a photon is calculated by
energyinJoules= Planck'sConstant*frequenceinHz

Planck's constant is 6.67e-34 joules
so as a practical matter, e-50j cannot be the energy of a photon, as frequency cannot be small as e-16 hz.
