Solve the given questions:

Question 1: You charge an object by rubbing it, and then shake it at 1 Hz. How much energy does each photon carry?

Question 2: Making estimates. The human eye can detect as few as 9760 photons per second entering the pupil. About how much energy is this, per second? (Assume the photons have a wavelength of 380 nm.)

Can someone please explain what the heck is going on?
