Laws of lenses and optical instruments
Principle: The focal lengths of unknown lenses are determined by measuring the distances of image and object and by Bessel's method. Simple optical instruments are then constructed with these lenses.
Tasks:
1. To determine the focal length of two unknown convex lenses by measuring the distances of image and object.
2. To determine the focal length of a convex lens and of a combination of a convex and a concave lens using Bessel's method.
3. To construct the following optical instruments:
1. Slide projector; image scale to be determined
2. Microscope; magnification to be determined
3. Kepler-type telescope
4. Galileo's telescope (opera glasses).
