TY - JOUR T1 - Súprava z geometrickej optiky GON A1 - Holec, Stanislav JA - Obzory matematiky, fyziky a informatiky Y1 - 2002 VL - 31 IS - 2 SP - 29 EP - 37 SN - 1335-4981 N2 - Autor of the paper has created a new set of teaching aids (GON ) to support physics education at all levels (primary, secondary, teachers training). The set contains untraditional optical elements (“they are made” from the air and surrounded by glass), which allow to show a lot of suprising and interesting experiments. Some of these experiments are introduced in this paper. In addition it is possible to do quantitative analysis of the data obtained from experiments by measurement distances, radiuses, sizes etc. ER -
