... Measure four slits on the card. The slits should be 1 inch long, o inch wide, and o inch apart. Center the slits in the middle of the card. An Exact-o knife works best for cutting because it creates the smoothest slits. It is important to avoid ragged or uneven edges. Cut the bottom and top from the ...

... • What are the evolutionary advantages of being sensitive to light, per se (versus some other part of the E.M. spectrum)? • Light is “bouncy”. Unlike longer-wave energy, which passes through many opaque objects, light can be reflected (‘bounced’) off of objects, making them visible. Light’s a better ...

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.
