How is fringe width of an interference pattern in Young.s double slit experiment affected if the two slits are brought closer to each other?

A : For best contrast between maxima and minima in the interference pattern of Young.s double slit experiment, the intensity of light emerging out of the two slits should be equa. R : The intensity of interference pattern is proportional to square of amplitude.
