How does relative brightness function in depth perception?

Relative brightness significantly informs depth perception by taking into account how we perceive the luminance of objects at varying distances from us. Objects that are farther away typically appear less bright than those that are nearer due to the scattering of light in the atmosphere and other environmental factors. This phenomenon occurs because light diminishes as it travels through the air, and distant objects often have a more muted and less intense brightness, giving us visual cues about their relative distance.

Option D suggests that farther objects appear brighter, which contradicts our experience, as atmospheric effects usually cause distant objects to lose brightness. Brightness does play a role in depth perception, which is inaccurately stated in option C, as our brains utilize luminance differences to judge distance and spatial relationships effectively.

Thus, understanding that objects farther away appear less bright than those that are close provides a fundamental basis for how we interpret depth and spatial arrangement in our environment.
