1. A linear object that is h = 1.75 m tall is placed a distance a = 0.780 m from a small light source. A shadow is produced on a screen that is a distance b = 1.17 m behind the object. Compute the height of the shadow.
2. A pinhole camera that is a = 10.20 cm long is placed a distance b = 19.0 m from a 4.35 m high object. Compute the size of the image produced by the camera.
