(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’.

hi prasanna maam

how did we conclude

a1/a2=sqroot(w2/w1)

and can u tell me which textbook contains this particular question ?

thank you

would like to see an answer to that as well… have you found one in these 2 days? please update if you did. thanks
