# Final Exam Review

```Final Exam Review
General Comments: My overall strategy for studying for the final would be to look
over all of the reviews and be able to understand that material well. I think that most of
the problems will be like the problems from the end of the chapters, but slightly tweaked
(if you compare the past exams to the homework assignments, they are pretty similar).
But, as always, do whatever works best for you.
Chapter 23:
Flat mirrors: be able to find the image location.
Concave Mirrors: Be able to find the magnifications, image or object height and the
locations of the image or object using the mirror equation. Understand Table 23.1 and be
able to use the appropriate sign convention for the mirror equation. Be able to understand
Figure 23.13 (how the object is real, virtual, where it is, etc..).
Images formed by refraction: Be able to calculate either the image/object location or
height using equations 23.7 and 23.8. Be able to use Table 23.2.
Thin Lenses: Be able to use the thin-lens equation to find either p, q, or f, and be able to
find the height of the object or image. Be able to use Table 23.3 for the thin-lens
equation. Be able to use the Lens maker’s equation and how to find either the radius of
curvature or the focal length. Be able to find the location of an image produced by both
converging and diverging lenses (for both one and two lenses in a row).
Problems: 4, 7, 8, 11, 17, 20, 21, 24, 25, 26, 27, 28, 29, 36, 43, 44, 51, 53, 54, 61
Chapter 24:
Young’s Double-Slit Interference: Be able to find the angle of the mth bright/dark fringe,
and where it is located on the screen.
Interference in Thin Films: Be able to calculate how many fringes there are for a wedge
(like we did in group problems). Be able to find the thickness, index of refraction, or
wavelength for a certain value of m. Know what the phase change is for n2>n1,n3 and
for n1<n2<n3.
Single-Slit Diffraction: Be able to find dark for a given value of m. Be able to find the
height of the screen as well. Be able to calculate the width of the central bright spot.
Diffraction Gratings: Be able to find bright for a given m as well as finding the
maximum number of bright spots you can see.
Polarization of Light Waves: Be able to use Malus’s Law and be able to use Brewster’s
Law (i.e. be able to find Brewster’s angle).
Problems: 4, 5, 7, 8, 14, 16, 20, 22, 23, 29, 31, 33, 34, 36, 38, 39, 43, 44, 46, 48, 50, 53,
54, 58, 59
Chapter 25:
Read and understand sections 25.2 and 25.3
Problems: 9, 10, 11, 14, 16, 17, 18, 19, 21
