... The ray approximation states that light travels in straight lines until it is reflected or refracted and then travels in straight lines again. The wavelength of light must be small compared to the size of the objects or else diffractive effects occur. ...

... This is a well-behaved expression as long as n0 n1. However, sinϑ0 can range from zero to unity, and, if n0 > n1 then there comes a point, as sinϑ0 increases, where the argument of the arcsin function becomes greater than unity and the expression can not be solved for a real ϑ1. The value of ϑ0 at ...

The angle between the slides is extremely small, so is said to be approximately zero in this analysis. The pat ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
