24.57. Set Up: Rays that pass through the hole are undeflected. All other rays are blocked. Solve: (a) The ray diagram is drawn in Figure 24.57. The ray shown is the only ray from the top of the object that reaches the film, so this ray passes through the top of the image. An inverted image is formed on the far side of the box, no matter how far this side is from the pinhole and no matter how far the object is from the pinhole. Figure 24.57 (b) The image is 2.4 cm tall. Reflect: A defect of this camera is that not much light energy passes through the small hole each second, so long exposure times are required. 24.58. Set Up: Solve: and The object is a distance of in front of the mirror and the image is a distance of behind the mirror. 24.59. Set Up: Since the image is projected onto the wall it is real and so m is negative and The object, mirror and wall are sketched in Figure 24.59. The sketch shows that Figure 24.59 Solve: and and The mirror should be 7.20 m from the wall.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
