Abstract

          The goal of our project was to photograph the filament of a light bulb as it burned out over time via the sweep photographic method.  Prior to the experiment, we hypothesized that immediately after being shot, the bulb filament would grow dimmer.  We tested our hypothesis by using the rotating mirror method and a camera to capture a bulb being shot by a pellet gun. We found that the impact of a BB with an ignited bulb actually causes a sharp rise in filament brightness directly after impact, with an overall rise of 4.2% brightness from controls.
