What can be said about a perfect mirror? (Note: i is the incident intensity, r is the reflected intensity, and t is the transmitted intensity.) O (e) (b) and (d) but not (a) and (c) O (d) t/i = 1 O (f) (a) and (c) but not (b) and (d) O (a) r/i = 1 O (b) r/i = 0 O (c) t/i = 0Suppose you have a convex lens with focal length of 50 cm. If an object is placed a distance of 1 meter from the lens, what is the distance between the image and the lens in meters? O (d) 1/2 O (e) -2 (virtual image) O (c) -1/2 (virtual image) O ( f) 1 O (b) 50 O (a) 1001 pts Light waves with wavelength L are incident upon a slit of width d. What is the best approximation of the width of the slit's image on a screen that is a distance x away from the slit? Assume (L/d)
