Thinking about the different laboratory techniques you have now mastered, suppose that you decided to use the motion detectors we used in lab. Standing on the side of a road, suppose you aimed the motion detector at a passing car. Make a plot of the distance vs. time graph you'd expect to get. From the distance vs. time graph in problem 4, you are now in position to make a speed vs. time graph by remembering that the slope of the distance vs. time graph is speed. This question is really asking what an image is.
Light moves away from an object in all directions.
Make a drawing to scale. For problem 10, calculate the position of the image using the formula on p. 324. Using the other formula on page 324, calculate the height of the image. Make a drawing to scale. For problem 12, calculate the position and height of the image using the formulae on p. 324.
