Clean scientific diagram of the double-slit experiment. Simple black-and-white line drawing. On the left: a light source emitting a narrow beam. In the center: a barrier with two thin slits labeled 'Spalt 1' and 'Spalt 2'. On the right: a screen showing the interference pattern with alternating bright and dark stripes. Straight arrows show the light beam direction from source → slits → screen. Include clear labels: 'Lichtquelle', 'Doppelspalt', 'Interferenzmuster'. Minimalistic, textbook-style, no color shading, clear and schematic. See more
