1. • Response of the eye. The human eye is most sensitive to
BIO green light of wavelength 505 nm. 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
receptor cells in the rods of the retina. (a) What is the fre-
quency of this photon? (b) How much energy (in joules and
eV) does it deliver to the receptor cells? (c) To appreciate what
a small amount of energy this is, calculate how fast a typical
bacterium of mass 9.5 x 10-12 g would move if it had that
much energy.
