Question

A Young’s double slit interference arrangement with slits S₁
and S₂ is immersed in water (refractive index = 4/3) as
shown in the figure. The positions of maxima on the
surface of water are given by x² = p²m²????²– d², where ???? is
the wavelength of light in air (refractive index = 1), 2d is
the separation between the slits and m is an integer. The
value of p is
