A small source of light at the bottom face of a rectangular glass slab 2.25 cm thick is viewed from above. Rays of light totally internally reflected at the top of the surface outline a circle of 7.6cm in diameter in the bottom surface. Determine the refraction index of the glass.
This is what I interpreted:
I can find out the angle of incidence and reflection (theta 1), but then I am stuck. please help.
