In a double slit experiment green light

In the double-slit experiment, a beam of light is aimed at a barrier with two vertical slits. After the light passes through the slits, the resulting pattern is recorded on a photographic plate. When one slit is covered, a single line of light is displayed, aligned with whichever slit is open. Intuitively, one might hypothesize that if both slits were open, the resulting pattern would display as two lines of light, aligned with the slits. What occurs in practice, however, is that light passing through the slits and displayed on the photographic plate is entirely separated into multiple lines of lightness and darkness in varying degrees.

In double slits experiment, for light of which colour the fringe width will be minimum. In Young's double slit experiment if wavelength of light is doubled without changing other conditions, the fringe width will. In Young's double slit experiment, the distance between the slits is 1 mm and that between slit and screen is 1 meter and 10th fringe is 5 mm away from the central bright fringe, then wavelength of light used will be. In Young's double-slit experiment the distance between the slits is 1 mm and that between slit and screen is 1m. If 10th bright fringe is 5 mm away from the central bright fringe, then wavelength of light used will be. In Young's double slit experiment, the slits are 3 mm apart. The fringe width in mm is.

In modern physics , the double-slit experiment demonstrates that light and matter can satisfy the seemingly incongruous classical definitions for both waves and particles. This ambiguity is considered evidence for the fundamentally probabilistic nature of quantum mechanics. This type of experiment was first performed by Thomas Young in , as a demonstration of the wave behavior of visible light. He believed it demonstrated that Christiaan Huygens' wave theory of light was correct, and his experiment is sometimes referred to as Young's experiment [6] or Young's slits. The experiment belongs to a general class of "double path" experiments, in which a wave is split into two separate waves the wave is typically made of many photons and better referred to as a wave front, not to be confused with the wave properties of the individual photon that later combine into a single wave. Changes in the path-lengths of both waves result in a phase shift , creating an interference pattern. Another version is the Mach—Zehnder interferometer , which splits the beam with a beam splitter. In the basic version of this experiment, a coherent light source , such as a laser beam, illuminates a plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate.

Although Christiaan Huygens thought that light was a wave, Isaac Newton did not. Newton felt that there were other explanations for color, and for the interference and diffraction effects that were observable at the time. First, light must interact with something small, such as the closely spaced slits used by Young, to show pronounced wave effects. Furthermore, Young first passed light from a single source the Sun through a single slit to make the light somewhat coherent. By coherent , we mean waves are in phase or have a definite phase relationship. Incoherent means the waves have random phase relationships. Why did Young then pass the light through a double slit? The answer to this question is that two slits provide two coherent light sources that then interfere constructively or destructively. Young used sunlight, where each wavelength forms its own pattern, making the effect more difficult to see.
