Question

Quizplus · Accepted Answer

The perception of brightness follows a logarithmic scale, not a linear one. Therefore, the initial increase from off (0 watts) to 50 watts represents a more significant perceived change in brightness than the subsequent increases, because the human eye perceives changes in brightness relative to the previous level of brightness.
