You use a 1.00 m long vertical stick to cas shadow (Figure 28-49). You can use the length of its shadow to determine other lengths or distances. On a bright sunny day, you find that at a certain time, the shadow cast by the stick is 3.00 m long. The stick is 100. m behind the tree, and you measure the shadow just before the Sun disappears behind the tree. What is the height of the tree? What assumptions did you make? h? 1 m 3 m 100 m Figure 28-49 Problem 23. 24. * A pinhole camera like the one in Figure 28-5(a) is 20.0 cm deep and has a hole 1.00 mm in diameter. A
