Optics Laboratory

At the end of Optics Laboratory course, the students should be able to: 1. identify different types of lenses and mirrors; 2. describe the nature of images formed by different lenses and mirrors; 3. differentiate between real and virtual images; 4. state the relationship between the object size and image size by a concave mirror as well as magnification; 5. determine the power of the convex lens as well as magnification; 6. describe how to set up the optical bench with lens holders, lenses, screen position to calculate focal length; and 7. explain the use of a meter rule in focal length determination.

Techniques learned in geometrical and physical optics are practiced using optical bench experiments; object-image relationship, with lenses and mirrors. Magnification. Aberration; Effect of prisms on rays. Ray tracing. Optical principles of lensometry.
