Summary[edit]
| Description |
Deutsch: Ein von rechts kommender Lichtstrahl aus einer grünen Punktlichtquelle divergiert start und fächert sich nach gut 40 cm bis etwa 3 cm auf. Stellt man eine halbkreisförmige Linse mit ihrem Brennpunkt in den Lichtstrahl, werden die Strahlen deutlich sichtbar parallelisiert. Eine Holz-Spielfigur (Hasenlehrer) mit einer Höhe von etwa 6,5 cm dient als Größenvergleich. Das Bild entstand in der Mathe-AC Lernwerkstatt in Aachen. |
