1. PHYS 222 SI Exam Review

2. What to do to prepare Review all clicker questions, but more importantly know WHY Review quizzes Make sure you know what all the equations do, and when to use them

3. These equations are used exclusively in LRC circuits These equations are what let you find the major constants that do not change with time. Remember, capital letters are not time dependent.

4. These equations are used to determine the root-mean square voltage and current in an LRC circuit

6. Not mentioned in class really

7. AC Current section on the Equation Sheet

9. What happens to a circuit at resonant frequency?

10. Example #1

11. Example #2

12. Example #3

14. Equation relating power, current, and voltage

15. Average power in an LRC AC circuit

16. Equations used to convert a voltage inside a transformer

17. Current and voltage in a transformer

19. Speed of light related to two constants

21. Equations relating the radiation pressure of an electromagnetic wave to the poynting vector and E and B.

22. Poynting vector. Note that the poynting vector is perpendicular to both E and B

23. The intensity of electromagnetic radiation, related to the E field.

26. The equations for reflection and refraction

27. The equation for intensity of light through a diffraction grating.

28. The equation used to find the critical angle between two interfaces. At angles equal to or greater than the critical angle, refracted rays stop going through the second medium. Instead they undergo total internal reflection. Sometimes light coming from one direction onto an interface doesn’t have a critical angle, but if the light goes the other direction, then the critical angle exists.

30. The master equation for both lenses AND mirrors

32. Magnification caused by a mirror or lens

33. Focal point of a spherical mirror

34. “Lensmaker’s Equation”

35. Look up

36. Spherical fish bowls is the main application of this equation

38. This is the equation for two-source interference, used to find where the bright fringes are. To find the dark fringes, replace m with (m+1/2)

39. Destructive interference.

40. Assuming small angles the equation on the previous slide gives this result, where R is the distance between the slits and the screen, d is the separation of the slits, m is an integer, and y is the height above the central interference maximum.

41. In single slit diffraction, you can use this equation to find the intensity as a function of the angle.

43. Thin film destructive reflection

45. Single-slit diffraction a is the width of the slit. This equation gives diffraction minima To get maxima, replace m with (m+1/2)

48. This equation combines the effects of two-slit interference and the diffraction caused by each of the slits independently.

49. Used to find the chromatic resolving power for a diffraction grating

51. Used to find the location of maxima for diffraction gratings
