a. Assume that photons of blue light are used to locate the position of a 2.80 g Ping-Pong ball in flight and that the uncertainty in position is equivalent to one wavelength. Explain the minimum uncertainty in the speed of Ping-Pong ball?
b. The Alveoli are tiny sacs of air in lungs having the average diameter is 5.0 x 10-5m. Determine the uncertainty in the velocity of an oxygen molecule (that is 5.53 x 10-26kg) trapped within a sac.
