Young's double slit Definition and 111 Threads

Young's interference experiment, also called Young's double-slit interferometer, was the original version of the modern double-slit experiment, performed at the beginning of the nineteenth century by Thomas Young. This experiment played a major role in the general acceptance of the wave theory of light. In Young's own judgement, this was the most important of his many achievements.

    Young's double slit experiment question.

    Hi I don't know whether this is a homework-type question or not, so I am posting it here. In young's double slit experiment the interference pattern is found to have an intensity ratio between bright and dark fringes as 9. What does this imply: (Below are the options provided in the book...

    Young's double slit experiment presentation

    I am doing a presentation for my high school physics class on light. I want to show the wave-particle duality of light, but first I want to show each separately. So I want to introduce Young's Double Slit Experiment to show the wave nature of light. The problem is... I apparently don't know...

    One more question about Young's double slit experiment

    Hi, I would like to know what would happen if we altered one of the slits by making it into a very very long tunnel (an optical cable that would run for a significant distance, but would come out on the other side of the screen almost in the same spot of its beginning). Would this destroy...

    Young's Double Slit vs. Diffraction grating

    I've been working on my Physics work when I scanned across a section and noticed something that bothered me. The equation: d sin (thetha) = m (wavelength). d is the separation and m is an interger. However, it said to find the bright fringes of a double slit (Young's Double Slit...

    Intensity in Young's double slit experiment problem.

    Hello all, I have a problem that requires some knowledge about Young's double slit experiment. The question is as follows: Imagine performing Young's experiment with one slit wider than the other so that the intensity passing the wider slit is four times as great as that passing the narrower...

    How to Identify Constructive Interference in Young's Double Slit Experiment?

    My question deals with Young's double slit experiment. This figure is a graphical representation of Young’s double slit experiment in which laser light passing through a pair of closely spaced slits results in a 2-source interference pattern. The laser light, incident from the top, is...

    When it comes to the Young's Double Slit Experiment, I'm just wondering

    For the Young's Double slit Experiment, I'm just wondering when it comes to finding the distance between the adjacent fringes (shown on the screen), why can't we just measure directly the distance between the adjacent fringes instead of having to measure the distance between 5 fringes and...

    Young's double slit experiment using polarised light

    How will the Fringe system in a Young's double slit experiment affected if, 1] a pair of polarising sheets P1 and P2, one before each of the slits S1 and S2, such that their transmission directions are parallel. 2] what will be the effect if the transmission lines are mutually orthogonal...

    Need help understanding problem about Young's double slit

    "In Young's double slit experiment, assuming the distance between the slits is 0.07mm and the wavelength of light used is 600 nm, when the screen is 70 cm away, what kind of interference is there." I'm not sure what I'm being asked to determine here. Plugging in the figures into the...
