When the team mixed their new membranes with cholera toxin, the interference pattern behaved precisely as predicted.
The test they designed should produce patterns like this, optical interference pattern.
When electrons or photons in a beam pass through the two slits, they act as waves and produce an interference pattern on the wall.
The returning light beams merge together at the beam splitter and create an interference pattern of light and dark regions where the light waves either cancel out or reinforce each other.
If we fire the individual photons and have detectors at the slit to find out which way each photon went the interference pattern disappears.
