	reflection reflection return of a wave from a surface that it strikes into the medium through which it has traveled. The general principles governing the reflection of light and sound are similar, for both normally travel in straight lines and both are wave phenomena. Objects are visible because of the light...

	Seismic reflection surveying seismic reflection surveying In seismic reflection surveying, seismic waves are propagated through the subsurface and the travel times are measured of those waves that return to the surface after reflection at geological surfaces. Knowledge of the velocities with which the subsurface transmits the... Read more
	albedo albedo , reflectivity of the surface of a planet, moon, asteroid, or other celestial body that does not shine by its own light. Albedo is measured as the fraction of incident light that the surface reflects back in all directions. A perfect reflector by definition has an albedo of unity, i.e., all... Read more
	Optical scanners Bar Code Scanner Background Many different types of bar code scanning machines exist, but they all work on the same fundamental principles. They all use the intensity of light reflected from a series of black and white stripes to tell a computer what code it is seeing. White... Read more
	octant octant, a reflecting navigational instrument for measuring the altitude of heavenly bodies, having an arc of one-eighth of a circle, but, because of its reflecting properties, capable of measuring altitudes of up to 90°.
