Lenses Aim: To determine the effect changing the object to the lens distance has on the distance at which the image is displayed Prediction: To make my predictions I decided to use a quantitive prediction method, the equation for this is: 1 = 1 + 1 focal length (cm) Object-lens distance Lens-image distance To use this method I will have to know the focal length of the lens. To do this we did a preliminary experiment where I put a lens opposite a window with a piece of paper behind. I moved the paper back and forth until the image of the outside became clear on the paper. The distance from the lens to the card, when the image is in focus gives the focal length. Having established the focal range of the lens was 10.5, and that at this distance the image would not become clear for infinity. Here is our predictions using the equation explained earlier: 11...
