<quiz display=simple> {Excepting cases where where quantum jumps in energy are induced in another object (i.e., using only the uncertainty principle), which would NOT put a classical particle into the quantum regime?} + high speed - confinement to a small space - low speed - low mass

{What are the units of Plank's constant?} - mass x velocity x distance - energy x time - momentum x distance + all of the above - none of the above

{What are the units of Plank's constant?} - mass x velocity - energy x time - momentum x distance x mass + all of the above - none of the above

{How would you describe Old Quantum Theory} - complete and self-consistent - complete but not self-consistent - self-consistent but not complete + neither complete nor self-consistent

{The first paper that introduced quantum mechanics was the study of } + light - electrons - protons - energy

{What are examples of energy?} - $\frac{1}{2}m{v}^2$ - mgh where m is mass, g is gravity, and h is height - heat + all of the above

{What are examples of energy?} - $\frac{1}{2}mv$ - momentum - heat + all of the above

{What was Plank's understanding of the significance of his work on blackbody radiation?} - he was afraid to publish it for fear of losing his reputation - he eventually convinced his dissertation committee that the theory was correct + the thought it was some sort of mathematical trick - he knew it would someday win him a Nobel prize

{What was "spooky" about Taylor's 1909 experiment with wave interference?} - The light was so dim that the photoelectric effect couldn't occur - The light was dim, but it didn't matter because he was blind. + The light was so dim that only one photon at a time was near the slits. - The interference pattern mysteriously disappeared.

{How does the Bohr atom differ from Newton's theory of planetary orbits?} - The force between proton and electron is not attractive for the atom, but it is for planets and the sun. - The force between planets and the sun is not attractive for the atom, but it is for proton and electron. + planets make elliptical orbits while the electron makes circular orbits - electrons make elliptical orbits while planets make circular orbits
