Question

Young’s double slit experiment is one of the quintessential experiments in physics. The availability of low cost lasers in recent years allows us to perform the double slit experiment rather easily in class. Your professor shines a green laser (568 nm) on a double slit with a separation of 0.105 mm. The diffraction pattern shines on the classroom wall 3.5 m away. Calculate the fringe separation between the fourth order and central fringe.

    Answer:

    19mm

    Explanation:

    Given:

    wavelength λ= 568nm

    L= 3.5m

    distance between the slits ‘d’ = 0.105mm

    Fringe width can be determined by the formula

    β = λL/ d => \frac{(568 *10^{-9})(3.5) }{0.105*10^{-3} }

    β = 0.019m => 19mm

    Therefore, fringe width on the wall will be 19 mm
