Document Summary
Summer 2017: unpolarized light passes through three successive ideal polarizers, each of whose axis makes a 30 angle with the previous one. What fraction of the light intensity is transmitted: 1/4, 1/8, 3/8, 9/32, 27/64. 0: what is the critical angle for the interface between water (index of refraction n=1. 33) and air, 45. 7 , 48. 8 , 52. 2 , 57. 2 , zero. When the light in the material with a higher index is incident at the critical angle, the refracted angle is 90 : n. 1 refraction of water n=1. 33): 1. 33, 1. 00, 0. 95, 0. 85, 0. 75. If the focal distance of the mirror is f, find the distance between the object and the mirror: f/2, f, 2f, lager than 2f, between f and 2f. 2 f: a certain lens focuses light from an object 2. 75 m away as an image 48. 3 cm on the other side of the lens.
