HW #8 Solutions
... Take the distance across the US to be about 3000 miles = 1.6×3000 km. light travels at 3 × 108 m/s = 3 × 105 km/s. So the time is 1.6 × 3000 km/(3 × 105 km/s) = 0.016 s = 16 milliseconds. In fact, the earth’s circumference is about 40, 000 km so light travels around the earth (say in an optical fibe ...

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.
