- A paperweight is made of a solid glass hemisphere of index of refraction 1.54. The radius of the circular cross section is 4.45 cm. The hemisphere is placed on its flat surface, with the center directly over a 1.90 mm long line drawn on a sheet of раper. a. What is the image distance (with the correct sign)? cm b. What is the magnification of the image? c. What length of line is seen by someone looking vertically down on the hemisphere? mmB. CONVERGING LENSES: After performing this activity, the students should be able to: Sketch the location of the image in the concave mirror, measure the distance and the height of the image, and describe the object and the image in every case. MATERIALS: Rufer PROCEDURES 2 Construct the image of the following, given the focal length, distance of the object (do) (f) and height of the object (ho) in centimeters. Describe the location of both the object and the image being constructed. Determine the exact distance and the height of the image. identify the case number of each. Complete the table below. NOTE: Arrows that represent the secondary axes should be in red color, arrow that represent the object and the image is in blue color as well as the line that shows the bending of light ray, the rest of the construction is in black color. That is why you will be needing 3 colored ballpen for this activity. Use another sheet of bond paper for your construction.
