Question

Increase the slit width to 1050 nm. What happens to the width of the central bright fringe? (Always remember to wait a few seconds for the simulation to catch up with the changes you made.)

    Answer:

    The width of the central bright fringe becomes narrower.

    Explanation:

    In case of Single Slit, diffraction will occur.

    Then In Single slit Diffraction, width of central fringe is

    x_c= 2D\lambda/a

    where D= distance between screen and slit

    a= slit width

    \lambda = wavelength

    Thus if Screen width increases keeping other factors same then width of cental fringe becomes narrower as

    x_c\propto 1/a

    The width of the central bright fringe becomes narrower.
