The Double Slit Experiment – Light at the beginning of the 19th century

At the beginning of the 19th century, the English physicist Thomas Young conducted a simple, yet groundbreaking, experiment with light. Light from a coherent light source falls through an aperture that has two narrow slits, finally hitting a viewing screen. Due to this interference pattern, Young could prove that light behaves like a wave.

At the fifth station, we compare the interference pattern emerging from a single slit with that from a double slit.
