    I recently heard about frustrated total internal reflection from a friend, unfortunately he could not tell me much about it. From what I can tell, this occurs when total internal reflection occurs, and hence when the incoming light beam is above the critical angle. Reading more about it, it seems as if the light does need to, at least on the atomic level, touch the air and therefore exceed the bounds of the glass for refraction to occur, though, it seems that during FTIR the light beam progresses a fair distance outside of the glass. I am not sure though if this light can be seen under certain conditions, what exactly causes this, and what dictates its properties and reason for occurring.

    Maybe the probability wave of the light does not totally reflect...or perhaps experiences some type of delay, and 'detonates' at a certain distance, creating a reaction similar to what happens during the double slit experiment. I am not sure about the ratio of this, if the photons are equally divided or not. My source also mentioned the use of quantum tunneling but did not iterate on it at all. Perhaps whatever amount of photons tunnel at the connection between the glass and air, and come back at the 90 degree bend?
