The data set of the diameters of the metal cylinders manufactured an automatic machine has sample size of n=28, mean of x= 49.94 mm and std. of S = 0.15 mm. Expected diameter of metal cylinder is µ = 50.00 mm. Can we be 95% confident that machine calibrated properly? Solution: v=n-1=27 ; ta/2=? P[X for 2 S VR μ+ (a Sl Vi -1-a =0.95

A collimated beam of sodium light (λ = 589.3 nm) is incident normally on a Wollaston prism constructed from calcite with wedge angle of 15°, as shown in the figure. The angle of deviation between the two emerging beams equals [the refractive indices of calcite at this wavelength are n|| = 1.4864 and n₁ = 1.6584] OA 15% 15° OA
