Further thermal control is obtained with a thin sheet of carbon nanotubes layered over a heat-reflecting surface, which helps to equalise the temperature throughout the vehicle.

The wavelength of the photons was calculated to be roughly 630 nm so the reflecting surfaces can be as small as possible and yet avoid refraction and reflectivity issues.
43.
When completed, the Hobby-Eberly telescope, with its 91 hexagonal mirrors providing an 11-meters-in-diameter reflecting surface, will be second in usable mirror size only to the Keck Telescope in Hawaii.

Broken and shocked by the brutal death of a son, a brother and a bridegroom, the family has covered every reflecting surface in the house, a Jewish gesture of mourning.
45.
The temporal evolution of the reflected radar pulse is interpreted in order to estimate the distance between the radar altimeter and the reflecting surface; surface irregularities can also be estimated.
46.
In the 1970s experiments were being performed to test aspects of quantum optics and showed that the rate of spontaneous emission of an atom could be controlled using reflecting surfaces.
47.
Secondly, the speed of sound may be directly measured using a small acoustic transducer and a reflecting surface, mounted at a known distance from the acoustic center of the transducer.
48.
Multiple reflection by two or more reflecting surfaces has been known since antiquity and was described by as such by Giambattista della Porta in his " Magia Naturalis " ( 1558-1589 ).
49.
The reflecting surface of the telescope is made of 1100 thin stainless-steel wires running parallel to each other for the entire length of the cylinder and supported on 24 steerable parabolic frames.
50.
The flat reflecting surfaces can be metal sheets, but are more often made of wire screen or rod elements parallel to the driven element, to reduce weight and wind loads on the antenna.
