Units
| nanometer | nm (wavelength of visible light: 400-700 nm) |
Interesting Fact
The human eye has three types of color receptors (cones) sensitive to red, green, and blue wavelengths
Key Scientist
Thomas Young
Proposed three-color theory of human vision
Philosophy
Color as perception shows that reality's properties depend on the observer. Color is not solely in the light or the eye, but emerges from their interaction. This demonstrates that our understanding of the physical world is shaped by our sensory experience and cognitive processes.
