Show the effect of refraction at elevation 90, 75 and 25 degrees. Compute the difference in elevation angle but also in terms of absolute position difference in km.

question is image  3.c

Determine and write out the indices for the plane shown in the diagram below.

Lenses with given radii. Object O stands in front of a thin lens, on the central axis. For this situation, each problem in the table (below) gives object distance p, index of refraction n of the lens, radius r, of the nearer lens surface, and radius r, of the farther lens surface. (All distances are in centimeters.) Find (a) the image distance i and (b) the lateral magnification m of the object, including signs. Also, determine whether the image is (c) real or virtual, (d) inverted from object O or noninverted, and (e) on the same side of the lens as object O or on the opposite side. (a) (b) (c) (d) (e) in r2 i m R/V I/NI Side +14 1.52 -42 +42 (a) Number Units cm (b) Number Units This answer has no units v (c) virtual v (d) noninverted ♥ (e) same

Light from a source A at (−1, 1) is reflected by a plane mirror placed along the x-axisto a receiver B at (2, 2).(a) For a given point (x, 0) between A and B on the x-axis, find the distance betweenA and (x, 0) and the distance between B and (x, 0). Your answers should dependon x.(b) Denote by D(x) the sum of the two distances you found in the part (a), thoughtof as a function of x. Find D0(x).(c) Find the absolute minimum of D(x) on the x-interval [−1, 2].(d) The light from source A reflected by the mirror to receiver B will travel theshortest distance possible (more precisely, light will obey Fermat’s principle). Atwhat point P on the x-axis between A and B does the light hit the mirror?
