Here is the question: The human eye is able to detect as little as 2.35x10^-18 J of green light of wavelenght 510nm. Calculate the minimun number of photons of green light that can be detected by the human eye

find the energy of a $single$ photon of green light of 510nm, which is a lot less than the minimum detection limit that you're given.

For example, say that the green photon has 15J of energy, and the minimum detection energy is 300J. How many photons have to hit the eye in order to be detected?
