A luminous source is placed a distance of D/3 cm in front of the first lens. a. Draw the ray diagram to locate the final image? (25 points) b. Use lens equation to find the location of the final image? (25 points) c. Determine the overall magnification of the system? (25 points) Do for practice and earn (25 points) for completion: 2. Calculate the magnification of an object placed D mm from a compound microscope that has a B/2 mm focal length objective and a B mm focal length eyepiece. The objective and eyepiece are separated by D cm. 3. Two converging lenses of focal lengths D cm on the left and D+5 cm on the right are separated by a distance L = D/3 cm. A luminous source is placed a distance of D/2 cm in front of the first lens. a. Draw the ray diagram to locate the final image? b. Use lens equation to find the location of the final image? c. Determine the overall magnification of the system? 4. The optical system consists of two lenses of focal lengths D cm converging lens on the left side and focal length B cm diverging lens is in the right side. They are separated by a distance L = A+5 cm. A luminous object is placed B cm in front of the first lens (left of the converging lens). a. Use the lens equation to find the position of final image? b. Determine the overall magnification of the system? Dr. Hetti PHY 156
