Exam # 3 Study Guide Lectures: 21  29 Lecture 21 (March 16) Law of Reflection Question: Two mirrors meet at an angle of 120 degrees. A beam of light hits the first mirror at 65 degrees relative to the normal and then reflects off of the second mirror. What is the angle between the final light beam and the normal of the second mirror? Answer: 180 – 120 – 65 = 35 degrees (within triangle) 90 – 35 = 55 degrees (complimentary angles) Lecture 22 (March 18) Curved Mirrors Question: An object is placed 25 cm in front of a concave mirror with a focal length of 10 cm. Find the distance between the mirror and the image and the magnification of the image. Answer: 1/di = 1/f + 1/do = 1/10 – 1/25 = 3/50 cm1 di = 50/3 cm (real image) m = di/do = (50/3)/(25) = 2/3 x (smaller, upright) Physics 012 1st Edition Lecture 23 (March 20) Refraction of Light Question: A beam of light has a wavelength of 550 nm traveling in air is incident on a transparent material. The incident angle is 40 degrees to the normal. The refracted beam is 20 degrees to the normal. Assume n = 1 for air. Find n for and speed of light through the transparent material. Answer: n2 = (1)sinθ1/sinθ2 = sin(40)/sin(26) = 1.47 n = c/v v = c/n = 2.04 x 10 8 m/s Lecture 24 (March 23) Total Internal Reflection – Fiber Optics Question: Find max value for θ1 to get total internal reflection in glass cylinder. Answer: ngsinθ = nasin90 = 1 θ1 = sin1(ngsinθ2/na) = 67.1 degrees
