Question
2 Electrons and Baseballs
According to de Broglie's hypothesis, every object- even a baseball - has a wavelength associated with its momentum.
Likewise, the Heisenberg uncertainty principle applies to every object- even a baseball. The mass of a baseball is
5.00 oz, or about 142 g.
(a) What is the de Broglie wavelength of an electron with a speed of 100 mph, or 44.7m/s?
(b) If the uncertainty in the speed of the electron is 1 mph what is the uncertainty in its position?
(c) What is the de Broglie wavelength of a 100 mph fastball - a baseball with a speed of 100 mph, or 44.7 m/s?
(d) If the uncertainty in the speed of the baseball is 1 mph what is the uncertainty in its position?
(e) Critical Thinking: Is the Heisenberg uncertainty principle a good excuse for a player who strikes out?
Why or why not?
Report all results in meters (m).
