Which of these factors does NOT affect light behavior through lenses?

The behavior of light as it travels through lenses is primarily influenced by specific factors that dictate how light is refracted or bent. The index of refraction is crucial because it measures how much light slows down and bends when entering a medium, like glass or plastic from air. The lens shape also plays a significant role, as its curvature determines the path that light will take once it passes through. Additionally, the thickness of the lens affects the degree of bending; specifically, thicker lenses generally have a greater impact on the speed and direction of light.

Ambient temperature, however, does not directly affect how light behaves through lenses. While temperature can influence the physical properties of a lens material (like its index of refraction to a minor extent), it does not fundamentally alter the optics of how light is focused or dispersed through it. Therefore, this factor stands out as NOT being a primary determinant in the overall behavior of light passing through lenses.
