PPT-Beer's Law Determine attenuation of radiant energy by scattering and/or absorption passing

Where is optical depth of layer Optical depth is path length required for attenuation to 1e of original energy Depends on attenuation coefficients and density Transmissivity is proportion of original energy remaining.

"Hot air" rises but "heat" can travel in any direction. That is why you can feel the heat of the cup wh Click to . Continue. Objective.
