on Tues or Tues/ThursĬlasses not otherwise provided for in this scheduledĬlasses starting after 5:45 p.m. on Thurs only (revised)Ĭlasses starting after 5:45 p.m. Exam Day/DateĬlasses starting after 5 p.m. Only classes that start at a non-standard time on their first meeting day each week will hold their exam during the examination period for classes not otherwise provided for in the schedule on December 9 at 4:00 – 7:00 p.m. would still have their final exam on Thursday, December 8 at 8:00 a.m. For example, a class meeting only on Wednesdays but beginning at 10:10 a.m. What is Brewster’s formula? What is Brewster’s angle? Sin (90 - p) = cos pSin p = n cos pSin p /cos p = n Tan p = n This is Brewster’s formula.Important: The time of an examination may not be changed after it is fixed in this schedule and has been posted on the Registrar’s websiteĮxaminations are scheduled according to the day and start time of the first meeting of the course each week and held in the regular assigned meeting room unless the instructor is otherwise notified. They don’t produce fringes because they are not coherent! Lecture 39 (December 8)Know how to derive n = tan p. Which of the following can be stated with certainty? Why do the two headlights of your car not produce fringes? It can be said with certainty that lots of photons will reach B. Detectors A and C are in the line of sight of the source and slits, with B midway between. The target area has three photo detectors: A,B, and C. Lecture 38 (December 5) A monochromatic light source has a pair of closely spaced slits. To solve for wavelength, you would use d (Y/L) = m . Young’s double slit equation is distance = d sin . The path difference equation for bright (constructive) interference is m, whereas the path difference for dark (destructive) is (m + ½). Lecture 37 (December 3)What does pH stand for? What is the path difference equation for bright (constructive) interference and dark (destructive) interference? What equation is Young’s double slit? What equation would you use to solve for wavelength?PH stands for potential Hydrogen. If it destructive interference, it is dark and minimum. If it is constructive interference, it is light and maximum. Lecture 36 (December 1) What determines color? If it is constructive interference or destructive interference what is it in terms of minimum/maximum, dark/bright? Color is not due to pigment, but is due to the interference effect. For concave mirror or converging lens, q could be positive (for real image) and could be negative (for virtual image). For convex & diverging lens, q is negative (meaning it’s always virtual). For convex mirrors & diverging lens, f is negative. Lecture 35 (November 21) What is the equation for calculating focal length? What are the values for each variable for eachdifferent type of mirror/lens?The equation for calculating focal length Is (1/p) + (1/q) = (1/f). Because it is a negative value it is inverted. If you plug the values in, you should get -1. You would then calculate magnification by using: m = -q/p. If you plug the values in, you should get q = 20 cm. You could calculate q using: (1/p) + (1/q) = (1/f). Lecture 34 (November 19) How would you calculate q and M if given f and p? Given that f = 10 cm and p = 20 cm. The images produced by diverging lenses are small, virtual, and upright as well. Lecture 33 (November 17)What are images produced by convex mirrors in term of real/virtual and inverted/upright? Whatabout the image produced from a diverging lens? Images produced by convex mirrors are small, upright, and virtual. Lecture 32 (November 14) Why is the ray that passes along the radius reflected back along the same line? R is the normal, the angle of incidence = the angle of reflection = 0. You calculate for focal length by using this equation: (1/p) + (1/q) = (1/f), where f is the focal length. The results tell you that if M = 1 it is the same size. You calculate magnification by using: M = hi/ho. Convex mirrors are good for shoplifting, rear mirror of a car &…. Concave mirrors are good for makeup application & … & dentists. The flat mirrors are shiny on one side and dark on the back. PHYS 102 1nd EditionFinal Exam Study Guide Lectures: 31-39Lecture 31 (November 12)What are the three types of mirrors? What are they used for? How do you calculate Magnification? What do the results tell you about the image? How do you calculate for focal length? The three types of mirrors are flat, concave, and convex.
