Blue or Red, Which Wavelength is Absorbed First?

Is the color of the first wavelength of light that is absorbed first blue or red?

When going deeper?

Let's take some random picture from the Bali diving. What color dominates?

k, this is an interesting question that can have different answers depending on the context. In general, the color of the first wavelength of light that is absorbed first can vary depending on the material or substance being observed. For example, in plants, the first wavelength of light that is absorbed is usually red or blue, as these are the wavelengths of light that are most important for photosynthesis. On the other hand, in a laboratory setting, the color of the first wavelength of light that is absorbed can be controlled by the type of filter or material used. In this case, it is not necessarily a matter of which color is absorbed first, but rather which color is allowed to pass through the filter. So, to answer your question, it is not as simple as saying blue or red is always absorbed first. It depends on the specific situation and the properties of the material being observed.
