Sorry for this little diversion, but it has occurred to me that physics has a bit of a logical contradiction and I think highly of the group's rational faculties here to help me sort this out.
If light travels at a. different speed for different colors in order to account for the rainbow of a prism, how fast is the. speed of light then? Is there real physics to optics? How can light know what direction to bend after it leaves the lens?
The speed of light is a physical constant. The frequency (or wavelength) of a photon determines its energy and therefore, to the human eye, its color. Longer answer: https://www.asu.edu/courses/phs208/patternsbb/PiN/rdg/color/color.shtml https://en.wikipedia.org/wiki/Photon_energy Our ability to perceive light, and construct models of what it's bouncing off in realtime, has presented interesting problems to many noted scientists over the years.
