2. The discrimination distance in microscopes is given by Ax = 1/Sin@x where A is the %3D wavelength of the light used and 0 is the angle of view of the lens. In a microscope that can see the lens at an angle of 60 degrees with 6000 Å light, according to the Heisenberg principle a) Find the velocity of a powder grain with 0.1 grams. b) If the electron were moving instead of powder grain, what would its speed be? Compare and interpret both results.

2. Use Heisenberg's uncertainty principle to make a more quantitative estimate of the precision with which the position and momentum of electrons can be found in the two-slit experiment. If you are able to see an interference pattern (i.e. separate a maximum from a minimum), what typical precision do you have on the wavelength of the electron, and thus what precision do you have on the momentum of the electron. Now apply Heisenberg's principle to work out the precision you have on the position of the particle. Does this help explain the wave-particle duality of electrons?
