Chapt. 35Geometrical Optics271b) Now say that you tip your corner reflector so that the corner is at the bottom and thereflector is symmetrical about a vertical axis. You fill the reflector with water assumingthere is some end panes to hold the water in.In this case what is the two-dimensionaldeflection angle for a beam coming in from infinity, reflected twice, and deflected out toinfinity?HINT:Reduce the problem to that of part (a) and make use of the law ofrefraction.035 qfull 10300 3 5 0 tough thinking: the rainbow, focusingExtra keywords:stationary points4. You have a spherical drop of water and draw a horizontal axis through its center. A beam oflight travels to the right and is parallel to the axis. It strikes the drop at an angleθrelative tothe normal to the drop. Inside the drop the beam is deflected at an angleθrefrrelative to thenormal using the usual incident/refracted beam conventions. Draw a big, clear diagram.a) Using geometry (e.g., the isosceles triangle theorem), and the laws of reflection andrefraction find an expression in terms of
