Superposition of waves and young’s double slit experiment
Young’s double slit experiment: This experiment was performed in 1801 by Thomas Young; he found a pattern of interference light from a distant source to the diffracted in passing through two grids, a result that contributed to the theory of the wave nature of light. This experiment is in quantum physics, and quantum physics is a type of physics of the atomics and subatomic levels and that means that the study is very small. The normal physics don’t apply at this level.
Young’s original formulation is very different from the modern formulation of the experiment and used a double slit. In the original experiment a narrow beam of light from a small hole at the inlet of a chamber is divided into two by a card of a width of about 0.2 mm. The card is held parallel to the beam that penetrates horizontally in guided by a simple mirror. The light beam had a width slightly greater than the width of the divider card so when this is positioned correctly the beam was divided into two, each passing a different side of the dividing wall. The result can be projected on a wall in a darkened room.
With the modern formulation design allows you to display both the wave nature of light as wave-particle duality of matter. In a dark room is let into a beam of light through a narrow slit. Light falls on a middle wall with two slits. On the other side of this wall is a projection screen or a photographic plate. When one of the grids is covered, appears only a single peak corresponding to the light from the slit open. However, when both are open instead of forming an overlapping image obtained with the slits open individually, as would occur if the lamp is made of particles, one obtains a set of interference with other bright and dark stripes. This interference pattern is easily explained from the interference of light waves by combining the light from two slits, so much like the...
