Talk:Opacity

From Wikipedia, the free encyclopedia

Opacity (Environmental) - is the attenuation of light. As a light source of intensity "Io" is transmitted through a medium, particulate within the flue gas blocks, i.e, attenuates, the energy of the transmitted beam resulting in beam of less intensity "Ir". The difference "Io - Ir" is referred to as the amount of opacity. Ddelmo (talk) 19:00, 5 January 2008 (UTC)Ddelmo (talk) 19:06, 5 January 2008 (UTC)JATT PunJAbi Manny singh
