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.
•61 SSM The function (x) displayed in Eq. 38-27 can describe a
free particle, for which the potential energy is U(x) = 0 in
Schrödinger's equation (Eq. 38-19). Assume now that U(x) = U, =
a constant in that equation. Show that Eq. 38-27 is a solution of
Schrödinger's equation, with

- 52. • Structure of a virus. To investigate the structure of BIO extremely small objects, such as viruses, the wavelength of the probing wave should be about one-tenth the size of the object for sharp images. But as the wavelength gets shorter, the energy of a photon of light gets greater and could damage or destroy the object being studied. One alternative is to use elec- tron matter waves instead of light. Viruses vary considerably in size, but 50 nm is not unusual. Suppose you want to study such a virus, using a wave of wavelength 5.00 nm. (a) If you use light of this wavelength, what would be the energy (in eV) of a single photon? (b) If you use an electron of this wavelength, what would be its kinetic energy (in eV)?
