The human eye is most sensitive to green light wavelength 505nm. Experiments have found that when people are kept in a dark room until their eyes adapt to the darkness, a single photon of green light will trigger receptors cells in the rods of the retina.
a. What is the frequency of this photon?
b. How much energy (in joules and electron volts) does it deliver to the receptor cells?
c. To appreciate how small this amount of energy is, calculate how fast a typical bacterium of mass 9.5E-12 g would move it if it had this much energy.?
