Question

4. Light passing through a liquid-filled test tube can be scattered, absorbed, or transmitted. a. Define scattering, absorption, and transmission as they refer to light interacting with matter (the physics definition in some dictionaries). b. Which interaction(s) above will reduce the amount of light that reaches a detector?

Answer 1

(4) (a) when beam of light interacts with particle of matter, it is redirected in several different directions and there is change in direction of propagation of light. This phenomenon is knonen vas Scattering of light, When the matter absorbs (captures) electromagnetic radiation, converting the energy of photons to the internal energy; the phenomenon is knowen as Absorption of light. In this energy is transferred from the radiation to the absorbing species. The phenomenon of moving of electro- magnetic waves undeflected and unaltered through the material or medium is known as Transmission of Light, (6) Scattering and Absorption will rudlice the amount of light, that reaches a detector .
