How much light is reflected
WebDec 10, 2024 · The light passes A, reflects from B, and returns to A. A would see the reflected light as having a lower frequency. Light carries momentum, so each photon kicks the mirror. The mirror recoils. So the photon does lose energy on being reflected. For a macroscopic mirror, this is a very small effect. WebThe light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object. Rarely however does just a …

WebThe reflected light produces a mirror image. The amount of light reflected by an object, and how it is reflected, is highly dependent upon the degree of smoothness or texture of the surface. When surface imperfections are … WebThe law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in …
WebMar 1, 1999 · For example, ocean surfaces and rain forests have low albedos, which means that they reflect only a small portion of the sun's energy. Deserts, ice, and clouds, however, have high albedos; they reflect … WebFeb 6, 2013 · google will offer you better figures, but from memory, ordinary daily mirrors reflect as little as 40-60% of light. Lasers require 99.99% for full-reflection mirror and 99.9% for front escape mirror. They usually have such figures only in narrow band of wavelengths. Infact, upon eye inspection, laser mirrors are transparent to most except ...
