Light & Image: Understand Absorption Effects

[richardz03]

I understand obviously that the image and light will be kept but it will become a little bit green. But what happen in a very specific way especially about absorption??

 

[Drakkith]

The green glass functions as an absorption filter, absorbing much of the light that doesn't fall within a specific range of wavelengths. In this case, the glass will absorb a significant amount of the light that falls outside of the area of the spectrum we call green. The absorbed light ends up heating the glass.

Note that the glass isn't converting the light into another color, it is simply filtering out certain ranges of wavelengths (and thus colors) so that they do not pass through, allowing only the range of wavelengths you want to pass through.
