h = Planck’s constant (6.626 × 10–34 J • s)
v = frequency (in s–1)
c = speed of light (3.0 × 108 m/s)
The eyes of certain reptiles pass a single visual signal to the brain when the visual receptors are struck by photons of a wavelength of 850 nm. If a total energy of 3.15 × 10−14 J is required to trip the signal, what is the minimum number of photons that must strike the receptor?
