SetupSetupAttentionTake care that the <strong>lens</strong>es lie with their flat sides precisely on the perpendicular <strong>of</strong> the crossedlines and that their position does not change during the experiment.Draw crossed lines at right angle to each other in the middle <strong>of</strong> your sheet <strong>of</strong> paper. Theintersection<strong>of</strong> the lines is point M.Make two marks, one on either side <strong>of</strong> M, at a distance <strong>of</strong> 3 cm away from M.Fig. 1Lay the planoconvex <strong>lens</strong> (rough side downwards) with the flat side precisely on the perpendicularline within the two marks.Insert the three-slit aperture in the light box on the <strong>lens</strong> side and position this about 10 cm fromthe plane edge <strong>of</strong> the block.Fig. 2- 4 -
