Suppose we now decrease the size of the pinhole by half. How should the wavelength of the incoming wave be adjusted so that now exactly 4 bright fringes lie inside the central bright fringe of the original case

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 × 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)
