4. Fig. 4a illustrates an experimental setup to compare the height of an object with image formed by a pin-hole camera. The Object height, d, is placed in front of a pin-hole camera and the height, h, of the image produced on a screen was measured. The Experiment is repeated for four more objects of different heights as shown in the diagram.

Fig.4b shows the heights d = d1, d2, d3, d4 and d5 of the object and the corresponding image heights h = h1, h2, h3, h4 and h5

• Measure and record the raw object heights d = d1, d2, d3, d4 and d5
• Convert the raw object heights to real object heights D = D1,D2,D3,D4 and D5 using the scale provided.
• Measure and record the raw image heights h = h1, h2,h3,h4 and h5
• Convert the raw image heights to actual heights H = H1,H2,H3,H4 and H5 using the scale provided
• Tabulate the results as shown below.

Plot a graph with actual image heights (H) on the vertical axis and the actual object heights (D) on the horizontal axis.     Graph is on Next Page

• Determine the slope of the graph
