reflection - In music

In physics, the bouncing off from a suitable surface of a beam of light, sound, or other wave at an angle equal to that of the incident beam. Light is reflected by shiny (eg metal) surfaces, and at a change in refractive index (eg in passing from air to glass). Sound is reflected by hard, smooth surfaces and in passing through a change in air density. Reflectance is the measured ratio of incident intensity to reflected intensity.
