In a single slit diffracton experiment, ...

In a single slit diffracton experiment, the width of the slit is made double the original width. How does this affect the size of the central diffraction band?

Text Solution

Verified by Experts

The width of the central maxima `=(2lambdaD)/(d)`. When d is doubled, the width reduces to half.

    The angular width of central maximum in a single slit diffraction pattern is 30^(@) . The width of the slit is 1 mu m. the slit is illuminated by monochromatic plane waves. If another slit of same width is made near it, Young's fringes can be observer on a screen placed at a distance 50 cm from the slits. If the observed fringe width is 1 cm, what is slit separation distance? (i.e., distance between the centres of each slit )
