The document appears to be a set of questions for students about a lecture on Heisenberg's Uncertainty Principle and quantum mechanics. It includes questions about the electron size compared to the neutron, Maxwell's equations and electrons in atoms, the cornerstone postulate of quantum mechanics, photons released when electrons change orbits, and the relationship between energy and wavelength. It also asks students to label diagrams of the helium and neon emission spectra and explain why there are more lines in neon. Further questions cover experiments by Newton, Boltzmann, and Young and the wave nature of electrons.

and work in groups to complete questions
1. What is the size of the electron compared to the neutron? (new)
2. What did Maxwell’s equations say about an electron in an atom?
3. Please stateand complete the corner stone postulate of quantum mechanics:
4. What is released when an electron falls from an outer orbit to a lower one?
5. What is the relationship between energy and wavelength (ie: an equation with planck’s constant)
5.A Walter Lewin-drew and energy spectrum- please describe it in a sentence or two

2. 6. How does DrLevin separate out the “light” (ie what does he give his students)?
7. What is a spectrum?
The light from Helium and Neon (11.14)
8. What do you expect to see when you disperse light from the light source? 12.53
9. What does Dr Levin say you will see on both sides of the grating? (mirror images of the sharp lines)

3. 10. Helium has only 2 electrons- can you label the Helium spectrum?

4. 12. Why are there more lines in the emission spectrum of Neon than that of Helium? (there are more
electrons )
13. What was the battle between Newton and Boltzman, and what did Newton believe light was like?
14. What was the experiment done by Young in 1801? (17.24)
15. What is the great mistery of Quantum mechanics? (17.49)
16. Chemistry students are often asked to calculate the de Broglie relationship or the de Broglie
wavelength of a baseball.
Determine the de Broglie wavelength for (a) an electron ( ) moving at a speed of
and (b) a baseball ( ) moving at a speed of 13 m/s.

5. How do you conceive electrons in an atom?
6.
Permanent Localization: Here the students were asked the question: “Does
an electron in an atom have a definite position at each moment of time?”
7. Heisenberg's uncertainty relation
Question: What is the meaning of ∆x and ∆p?
4. Photons
We now want to describe in more detail the contents of the course:
(i) Photoelectric effect

6. (ii) Preparation of dynamical properties
(iii) Wave and particle behavior in a Mach-Zehnder interferometer
(iv) The probability interpretation of quantum mechanics
17. Electrons
(i) Wave behavior of electrons
(ii) Double-slit experiment and probability interpretation

This week, Onetime and I had fun exploring some different ways of creating rainbows at home
and we’re going to share those with you toda
