How is the index of refraction of light in water determined?
Materials: o Graph paper o Felt tip pen o Ruler o Semicircular plastic dish o water Procedure I: 1) Draw a line dividing the graph paper in half. 2) Use a felt-tip pen to draw a vertical line at the center of the straight edge of the plastic dish. This line will be your object. 3) Place the edge of the dish along the straight line so that the dish is on the bottom half of the paper. Trace the outline of the dish on the paper. 4) Mark the position of the object on your paper. 5) Add water until the dish is ¾ full. 6) Lay a ruler on the bottom half of the paper. Adjust the position until the edge of the ruler seems to point at the object when you look through the water. 7) Have a lab partner check to verify that the ruler position is accurate. 8) Draw a line along the ruler edge to the edge of the dish. 9) Repeat steps 6-8 for a different position of the ruler. Procedure II: 1) Wipe the vertical line from the dish and draw a vertical line at the center of the curved edge. This is your ne
