In the figure shown S is the saurce of white light kept at a distance x_(0) frorn the plane of the slits. The source moves with a constant specd u towards the slits on the line perpendicular to the plane of the slits and passing through the slit S_(1) . Find the instanteneous velocity (magnituce and direction). of the central maxima at time t having range 0 le t lt lt (x_(0)-d)/(u) . Assume that D gt gt d .

A parallel beam of monochromatic light is used in a Young's double slit experiment. The slits are separated by a distance d and the screen is placed parallel to the plane of the slits. If the incident beam makes an angle theta = sin^(-1)((lambda)/(2d)) with the normal to the plane of the slits, there will be .....at the centre P_(0) of the pattern.

In a double slit interference experiment, d is the separation of the slits and D is the distance of the screen from the plane of the slits. When white light is used, a dark band of wavelength lambda is formed, directly in front of one of the slits. Then the value of lambda is
