In a Young s double slit experiment, the ratio of the slit s width is 4 :1The ratio of the intensity of maxima to minima, close to the central fringe on the screen, will be:

Question

Accepted Answer

Correct answer: B. (b) JEE Main 2019 Let I_1 ,I_2are intensity of light coming from two slits. As, I ∝W ∴ I_1I_2= 41 I_1=4I_0 I_2=I_0 I_ maxI_ min= ( I_1+ I_2)^2( I_1- I_2)^2= ( 91 ) = ( I_1I_2+1 I_1I_2-1 )^2 = ( 4+1 4-1 )^2= 91
