Principle

Generally, the law of imagery is first derived theoretically or
- depending on the class situation - simply stated and then
experimentally confirmed or tested. The experimental testing can be
conducted as suggested above. It is also conceivable that the above
procedure could be used without previous knowledge of the law of
imagery, then however the students do not know why the reciprocals
of f, g and b are formed. This is also the case when they are
simply told what the law is.

Benefits


Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench

Extension with others sets at anytime, no additional light sources needed, recognition value for students



Tasks

Which law is valid for images formed by a concave mirror?
Investigate the correlation between the focal length, the object
distance g and the image distance b which exists when real images
are formed with a concave mirror.
