In a Young's double slit experiment, a monochromatic source of wavelength lambda is used to illuminate the two slits S_(1) and S_(2). The slits S_(1) and S_(2) are identical and source S is placed symmetrical as shown. Interference pattern is observed on a screen at a distance D from the centre of slit. The distance between the slits is d. If the size of slit S_(1) is slightly decreased, then

1.	In a Young's double slit experiment, a monochromatic source of wavelength lambda is used to illuminate the two slits S_(1) and S_(2). The slits S_(1) and S_(2) are identical and source S is placed symmetrical as shown. Interference pattern is observed on a screen at a distance D from the centre of slit. The distance between the slits is d. If the size of slit S_(1) is slightly decreased, then

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
A concave lens with equal radius of curvature both sides has a focal length of 12 cm. The refractive index of the lens is 1.5. How will the focal length of the lens change if it is immersed in the liquid of refractive index 1.8 ?
