## Description

Photographic diffraction objects in a slide frame.

Review: Bestellt für den Physikunterricht in der elften Klasse - hat sauber funktioniert. Werden wir zwar potentiell danach nicht mehr benötigen, aber für den Versuch hat es sich gelohnt.
Review: E' sufficiente un laserino rosso da pochi euro per vedere una buona figura di interferenza. Si riesce anche a determinare abbastanza bene la lunghezza d'onda del laser. Ho provato l'esperienza di Young con un laser rosso ed uno blu; le due figure appaiono differenti (come è giusto che sia) e i "conti" tornano.
