A coherent plane wave comes into the double slit, and thanks to Huygens's principle, the slits filter-out only the point sources on the plane wave that can pass through them, turning the plane wave into two separate radial waves, which then interfere with each other.

- 8.7: Double-Slit Interference
Photons or matter (like electrons) produce an interference pattern when two slits are used. Light from a green laser passing through two slits 0.4 mm wide and 0.1 mm apart. In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior of both classical particles and classical waves.
3 Ιουν 2020 · The double-slit experiment is a test that demonstrates light can fundamentally display both wave and particle features, also known as wave-particle (photon) duality. It consists of two closely-spaced slits in front of a light source such that a beam of light passing through them is split and projected on a screen placed far from the slits.
2 ημέρες πριν · The double-slit experiment is an experiment in quantum mechanics and optics demonstrating the wave-particle duality of electrons, photons, and other fundamental objects in physics.
20 Ιαν 2023 · The double-slit experiment is a famous experiment which demonstrates light diffraction through two small slits (openings). Since in this experiment there are now two openings through which the incoming wavefronts encounter, there are two nearby light sources that are generated at each slit according to Huygens' Principle.
Explain the phenomena of interference. Define constructive interference for a double slit and destructive interference for a double slit.
Example 14.1: Double-Slit Experiment Suppose in the double-slit arrangement, d =0.150mm, L =120cm, λ=833nm, and y =2.00cm . (a) What is the path difference δ for the rays from the two slits arriving at point P? (b) Express this path difference in terms of λ. (c) Does point P correspond to a maximum, a minimum, or an intermediate condition?
