1. Referring to “Figure 1-Part
A the double slit”, please select the correct relationship between q, d, and ml.
(a) tan q = ml
/ a
(b) tan q = d / ml
(c) sin q = ml
/ d
(d) sin q = ml
/ a
(e) sin q = d / ml

2. Referring to “Figure 2-
The double slit interference pattern”, please select the correct relationship
between q, y, and D.
(a) tan q = y / D
(b) tan q = D / y
(c) cos q = y / D
(d) sin q = y / D
(e) sin q = D / y

- What
happens if the aperture, a, is starts approaching (becoming very small) value
of lambda, l?
- The
patterns spread out too far to measure
- The
patterns start merging together
- A
set of fringes will be superimposed on the double-slit interference pattern
- The
interference patterns will become progressively “sharper”

- (This
question is worth 50% of your pre-lab, and is your opinion) What was
your favorite part of the lab?
- In
lab lecture with PowerPoints
- In
lab lecture using the chalk board (although this was very limited)
- The
pre-lab aspect of preparing you for the lab
- Posting
of the PowerPoints so that you had example data while performing
analysis
- Group
quizzes
- Full
page graphs by hand to minimize uncertainty
