Summary

[edit]
Description
English: Using a 420nm violet laser pointer, the beam fluorescates in a triangle of normal household glas.

Total internal reflection causes it to be reflected many times at the top and at the bottom and also two times at the 45° side angles.
Colors: The violet light looks blue to the photo, the fluorescence looks more green.

Where total internal reflection happens a little of the light escapes, so these points look blue.
Deutsch: Mit einem violetten (420nm) Laserpointer entsteht grünliche Fluoreszenz in einem Glasdreieck.

Totalreflexion spiegelt den Strahl oft an der Oberseite und Unterseite sowie zwei mal an den 45° Seitenflächen.
An den Stellen der Totalreflexion entkommt ein wenig Licht, deshalb erscheinen diese Stellen violet.
Der Foto stellt das violette Licht als blau dar, auch die Fluoreszenz sieht grünlicher aus mit dem Auge.

Das Glas ist 1cm stark, der Glaser hat es mir für 5€ gebrochen, die Seiten sind unbearbeitet.
