The refractive index of light in glass varies with its wavelength according to equation mu (lambda) = a+ (b)/(lambda^(2)) where a and b are positive constants. A nearly monochromatic parallel beam of light is incident on a thin convex lens as shown. The wavelength of incident light is lambda_(0) +-Delta lambda where Delta lambda lt lt lambda_(0) . The light gets focused on the principal axis of the lens over a region AB. If the focal length of the lens for a light of wavelength lambda_(0) is f_(0) , find the spread AB.

Three narrow slits A, B and C are illuminated by a parallel beam of light of wavelength lambda , P is a point on the screen exactly in front of point A. Slit plane is at a distance D from the screen (D gtgt lambda) . It is know that "BP – AP ="(1)/(3) (a) Find d in terms of D and lambda (b) Write the phase difference between waves reaching at P from C and A. (c) If intensity of P due to any of the three slits individu- ally is I_(0) , find the resultant intensity at P.
