In this Special Feature, we present two reviews that should assist instructors and teachers at all levels in taking the step toward clicker use and choosing an appropriate model. Clickers can be detrimental if poorly used, but highly beneficial if good practices are followed, as documented in a growing body of educational literature. Moreover, like any classroom technology, clickers will not automatically improve teaching or enhance student learning. For those who have not yet tried teaching with clickers and may have heard unsettling stories about technical problems with earlier models, the decision to use them and the choice of an appropriate brand may be difficult. 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.Use of the audience response devices known as “clickers” is growing, particularly in large science courses at the university level, as evidence for the pedagogical value of this technology continues to accumulate, and competition between manufacturers drives technical improvements, increasing user-friendliness and decreasing prices.

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.
