Learning objects Far out lenses

TLF ID L56

Look at the Moon through a simple telescope. Adjust the focal length of two convex lenses and compare the results. Explore relationships between optical variables such as focal length, position of objective lens, convexity, image inversion and lens size. This learning object is one in a series of two learning objects. The series is also packaged as a combined learning object.
