Display Enlargements from Single Frame Motion Pictures

A Glass rod in spite of its transparency is quite visible. The reflections from its surface and interior and the imaging of other objects by refraction make it easy to see. If the rod is lowered into a glass of water, it becomes much less obtrusive and sharply defined; immersed in glycerine, it is practically invisible. Changing the rods environment from air having a refractive index widely different from glass to glycerine with the same index as glass has prevented surface reflection and destroyed the power to deflect a light beam and form images.
