Refraction Defraction Reflection

  1. May 6, 2010 #1
    A laser beam traveling in air strikes the mid-
    point of one end of a slab of material with
    index of refraction 1.45 as shown in the figure
    below.

    Dimensions of Block 46mm (L) and 3.4mm (W)
    Initial ray of light enters the slab from the left side at an angle of incidence of 39 degrees.


    Find the number of internal reflections of
    the laser beam before it finally emerges from
    the opposite end of the slab.

    You phrase that as if it were your homework question.
