Figure 4.4.1 4.4. 1: Diffraction from a double slit. The purple line with peaks of the same height are from the interference of the waves from two slits; the blue line with one big hump in the middle is the diffraction of waves from within one slit; and the thick red line is the product of the two, which is the pattern observed on the screen.
The photograph shows multiple bright and dark lines, or fringes, formed by light passing through a double slit. Example \(\PageIndex{1}\): Finding a Wavelength from an Interference Pattern Suppose you pass light from a He-Ne laser through two slits separated by 0.0100 mm and find that the third bright line on a screen is formed at an angle of \(10.95^{\circ}\) relative to the incident beam.
Aug 6, 2024 · Double Slit Interference. Young's double-slit experiment produces a diffraction and an interference pattern using either: The interference of two coherent wave sources. A single wave source passing through a double slit. In this typical set-up for Young's double slit experiment: The laser light source is placed behind the single slit.
Double-slit experiment. 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.
Displacement of Fringes in YDSE. When a thin transparent plate of thickness ‘t’ is introduced in front of one of the slits in Young’s double slit experiment, the fringe pattern shifts toward the side where the plate is present. The dotted lines denote the path of the light before introducing the transparent plate.

The acceptance of the wave character of light came many years later when, in 1801, the English physicist and physician Thomas Young (1773–1829) did his now-classic double slit experiment (see Figure 1). Figure 1. Young’s double slit experiment. Here pure-wavelength light sent through a pair of vertical slits is diffracted into a pattern on ...
