The man who discovered that even individual light particles have wave characteristics was: newton christian taylor planck

Taylor

Explanation:

Taylor found that with either high- or low-intensity light, a typical diffraction pattern was formed. Long exposure times were needed to develop the diffraction bands; one of the exposures needed three months to complete. With a series of photographic plates, he showed that even individual light particles, photons, have wave characteristics.

i was thinking more like reflects green light, just not sure

answer; how far out of place which the object finished relative to the starting location;
