Side note. I have always wondered, if we can hear the multiple frequencies caused by wave interference in soundwaves (e.g. square vs sine), why can't we see multiple frequencies in light waves. I assume it's just too fast?
- amluto 4y agoWe can, but we lump them into three bins, L, M, and S. The usual red, green, and blue are derived from those. L, M, and S are sensed by different cells. https://en.m.wikipedia.org/wiki/LMS_color_space https://en.m.wikipedia.org/wiki/LMS_color_space Similarly, our ears are sensitive to a rather larger number of frequency bins, and and each sensory cell senses one of these bins. Neither of these sensory mechanisms is particularly sensitive to phase and, in fact, we can’t hear phase differences very well.
- SamBam 4y agoIt's more useful in an evolutionary sense to look at a banana and see that it's yellow, than to feel distinctly that your red and green cone cells are each being stimulated separately. The combination happens in our brain because it's transforming those separate signals into useful information.
