A thin flake of transparent material (n = 1.51) is used to cover one slit of a double-slit interference arrangement. The central point on the screen is now occupied by what had been the 7th bright side fringe (m = 7). If λ = 549 nm, what is the thickness of the flake in meters? Number Units

(a) Figure (a) shows a nonconducting rod of length L = 8.30 cm and uniform linear charge density λ = +9.48 pC/m. Take V = 0 at infinity. What is V at point P at distance d = 6.50 cm along the rod's perpendicular bisector? (b) Figure (b) shows an identical rod except that one half is now negatively charged. Both halves have a linear charge density of magnitude 9.48 pC/m. With V = 0 at infinity, what is V at P? (a) (b) (a) Number i Units (b) Number Units

Figure (a) below shows a lens with radius of curvature R = 5.9 m and the diameter D = 22 mm lying on a flat glass plate and illuminated from above by light with wavelength λ = 628 nm. Figure (b) below (a photograph taken from above the lens) shows that circular interference fringes (called Newton's rings) appear, associated with the variable thickness d of the air film between the lens and the plate. In this Newton's rings experiment (a) how many bright rings are produced? (b) How many bright rings would be produced if the arrangement were immersed in water (n = 1.33)? (a) (b) (a) Number Units (b) Number Units
