You have been tasked with conducting an experiment on a pinhole camera to present at the school's science fair. To do this, you decide to build a simple pinhole camera using a cardboard box, where a small hole on the side allows light to enter and form an image on the wall opposite the hole. Your camera has the following dimensions: 30 cm width, 40 cm height, and 50 cm length. An object is placed 2 meters away from the camera and has a height of 24 cm. Suppose the image is formed at the back of the box. a) Calculate the height of the image projected on the back of the camera using the proportion between the distances; b) Determine the necessary space between the pinhole and the opposite wall for the image to be in focus; c) Describe the procedure you would follow to conduct the experiment, considering the positioning of the camera, the object, and the lighting conditions.
