What about a more conventional perception of a flash of light? Experiments have shown that a dark-adapted human will report visual sensation when 3.5 x 10-15 J of energy enter the iris, if the wavelength is near the peak of the eye's sensitivity (510 nm). How many photons is this? (In fact only 10% of these are absorbed by the retina, and thus contribute to the physical process of vision.) 3. Use conservation of energy to calculate the speed of an electron when it is in the ground state of a hydrogen atom (ionization energy 13.6 eV). What is the de Broglie wavelength of this electron? Does the value make sense?
