Reflecting \Re*flect"ing\, a.
1. Throwing back light, heat, etc., as a mirror or other
surface.
2. Given to reflection or serious consideration; reflective;
contemplative; as, a reflecting mind.
{Reflecting circle}, an astronomical instrument for measuring
angless, like the sextant or Hadley's quadrant, by the
reflection of light from two plane mirrors which it
carries, and differing from the sextant chiefly in having
an entire circle.
{Reflecting galvanometer}, a galvanometer in which the
deflections of the needle are read by means of a mirror
attached to it, which reflects a ray of light or the image
of a scale; -- called also {mirror galvanometer}.
{Reflecting goniometer}. See under {Goniometer}.
{Reflecting telescope}. See under {Telescope}.
Goniometer \Go`ni*om"e*ter\, n. [Gr. ? angle + -meter: cf. F.
goniom[`e]tre.]
An instrument for measuring angles, especially the angles of
crystals, or the inclination of planes.
{Contact, or Hand}, {goniometer}, a goniometer having two
movable arms (ab, cd), between which (at ab) the faces of
the crystals are placed. These arms turn about a fixed
point, which is the center of the graduated circle or
semicircle upon which the angle is read off.
{Reflecting goniometer}, an instrument for measuring the
angles of crystals by determining through what angular
space the crystal must be turned so that two rays
reflected from two surfaces successively shall have the
same direction; -- called also {Wollaston's goniometer},
from the inventor.
