(a) The ratio of the widths of two slits in Young’s double slit experiment is 4 : 1. Evaluate the ratio of intensities at maxima and minima in the interference pattern.
(b) Does the appearance of bright and dark fringes in the interference pattern violate, in any way, conservation of energy ? Explain.
b) There is NO violation of the conservation of energy. The appearance of the bright and dark fringes is simply due to a ‘redistribution of energy’.
