What is Interference?
Interference is a phenomenon that occurs when two waves superpose to form a resultant wave. This can be constructive or destructive interference, depending on the phase difference between the waves. When two waves are in phase, they will combine to create a larger wave. When they are out of phase, they will cancel each other out. This can be observed with all types of waves, but is particularly evident with light waves. The phenomenon can be explained using the wave model of light, but a deeper understanding of interference requires knowledge of wave-particle duality. If the waves are correlated or coherent with each other, then the resultant amplitude at a point is the vector sum of the amplitudes of the individual waves. If the waves are in phase, then they will produce a maximum displacement at a point. If the waves are in anti-phase, then they will produce a minimum displacement at a point.
Quantum interference is a strange and mysterious phenomenon that occurs when two or more quantum wave-functions overlap. Unlike classical interference, which can be explained using simple mathematics, quantum interference is still not fully understood. Specifically what is causing the wave function collapse when observed.
Quantum interference occurs when the wave-function interferes with itself. This can happen when two or more waves overlap, creating an interference pattern. The…
