In YDSE the screen is at distance D from the plane of the slits and slits are illuminated by monochromatic light of wavelength A Pis a point on screen at distance y from central maxima If by some arrangement the slits be moved symmetrical apart with relative velocity v the number of fringes crossing the point P per unit time will be yv 21 D yD V D vy
