... INVESTIGATING THE FACTORS WHICH AFFECT THE IMAGE FORMED BY A CONVEX LENS APPARATUS Light box, screen, slide, stand, lens, power pack and metre rulers. METHOD 1. I set up the apparatus as shown in my prediction. 2. I then turned the light on putting it on 10v. 3. I then, by using a ruler, placed the lens 70cm away from the object. 4. I then moved the screen closer and further away from the lens in order to get a clear picture projected onto the screen. 5. When I had a clear picture, I measured the length between the lens and the screen. I recorded the result. 6. I will then move the lens 5cm closer to the light box and repeat steps 4 and 5. 7. I moved the lens 5cm closer to the object until I had ten sets of results. 8. I repeated steps 1 to 7 twice in order to get an average. RESULTS LENS FROM OBJECT (cm) LENS
