In young’s double slit experiment (with identical slits) the intensity of a maxima is I. P is a point on the screen where` 10^(th)` maxima is formed with light of wave- length `lambda = 6000 overset(@)A`. Find the intensity at point P if the entire experimental set up is submerged in water of refractive index `mu = (4) /( 3)` . Assume that intensity due to individual slits remains unchanged after the system is dipped in water.
