In a Young's double slit set up, the wavelength of light used is 54nm. The distance of screen form slits is 1m. The slit separation is 0.3mm.  (a) Compare the intensity at a point P distant 10mm from the central fringe where the  intensity is `I_0`.   (b) Find the number of bright fringes between P and the central fringe.
