1)Set up the light source so that it is plugged in and lying down on the table (not on the bench), with the 5-line pattern selected so that it projects five beams of light. Place the cylindrical convex lens, standing up on the table, in front of it so that the middle beam goes right through the center of the lens (the beams should be perpendicular to the length of the flattened lens). Which beams are deviated? Which beams are not deviated? The five beams (simulating a very distant light source - see what happens in the thin lens equation if the object distance goes to infinity) should meet at the focus. The distance from the focus to the center of the lens is the focal length f. What is the focal length of this lens? Please answer the question that are in Bold letters.
