As I was walking along the pot and pan isle of Wal-Mart, I notice that the light gray tiles were reflecting the overhead lighting. Not only did I recognized the tiles reflecting the light coming from the light bulbs but I also acknowledged the natural coming from the sky light. The rays coming from the sky light, the incident ray comes in from the ceiling hitting the light gray speckled floor, or the “reflecting surface”, then crosses the normal line. The image I see on the Wal-Mart floor is the reflected ray. When standing close to the reflected image, I perceived that the degree of the angle of incidence is small because the incident ray comes in straight down causing a small incidence ray. Since the angle of incidence equals the angle of reflection that too must be a minuscule degree as well. This observation can be seen in the picture that I took.

  1. Interesting picture!
    You are a very good observer, who would have thought that one can see Physics concepts on WalMart's floor!
    Good explanation on your physics.
