The change in path length changes the required light-travel-time of each quantum of light, which results in different arrival times and causes a shifting in the interference pattern that results.

When you passed light through a double slit, it behaved just the same way that water waves do, producing that familiar interference pattern.

From the quantum perspective, however, light is a stream of photons. To explain the interference pattern, physicists say that each photon travels through both slits simultaneously and then ...

When Young shone light through his apparatus, he saw a pattern of bright and dark fringes that could only be explained by the interference of wavefronts. In the 1920s it was shown that the same ...

The fact that light forms interference patterns was strong evidence that light behaves like a wave, even though it also behaves as though it is made up of particles.

The canals can be understood in several equivalent ways: in terms of destructive interference between positive- and negative-order diffracted beams (that is Fourier components of the patterns); by the ...

The double-slit experiment, originally designed by Thomas Young in 1801, shows that light can form interference patterns, typical of waves. However, when scientists try to determine which slit the ...

Researchers discovered brand new interference patterns in twisted two-dimensional tungsten ditelluride lattices. These patterns can be tuned to look like periodic spots or even one-dimensional bands ...
