When the light ray illustrated in the figure below passes through the glass block of index of refraction n = 1.50, it is shifted laterally by the distance d. (Let L = 2.58 cm and θ = 33.0°.) (a) Find the value of d. It might help to carefully redraw the figure making the incident angle much larger than 33.0°. Make the figure fairly large so you can identify various angles on the figure. cm (b) Find the time interval...
