I tested out various reflector shapes - narrow parabolic reflectors and wide parabolic reflectors - to see which one was the most efficient. I measured the temperature change of the focus and the surface to measure the efficiency. The greater the temperature change, it indicates that the heat was more concentrated and absorbed. I tested out three models of parabolic reflectors and their curvature is shown below. I predict that reflector 2 would have the highest temperature increase since it is not too wide or narrow so it can converge light rays into one point more efficiently.
