A ray of light strikes a thick sheet of glass (n = 1.5)at an angle of 46° with the normal.Find the angle of the refracted ray within the glass with respect to the normal.

Using Snell's law, we have sin(i)/sin(r) = n, where i is the angle of incidence and r is the angle of refraction. Rearranging, we get sin(r) = sin(i)/n. Plugging in the values, we have sin(r) = sin(46°)/1.5 = 0.507. Taking the inverse sine of this value, we get r = 29°. Therefore, the angle of the refracted ray within the glass with respect to the normal is 29°. The correct choice is C.
