3D Laboratory // Experiment No. 02
The pattern of interference
Two stones falling into the same pond. Where the waves meet, the water decides: double up or cancel out. Drag the sources and draw the pattern yourself.

What are you looking at?
Waves add up
Superposition principle: when two waves cross, the surface responds to the sum of both. Turn off the 2nd source and you see perfect circles; turn it on and the pattern is born.
Constructive interference
Where the path difference is a whole number of wavelengths, crest meets crest: the wave doubles. These are the bright rays fanning out from the axis between the sources.
The dead lines
Where a crest meets a trough, the water never moves: nodal lines. This very pattern, made with light, is the double-slit experiment that revealed the wave nature of matter.
