Which type of scientific statement is this?

A theory is a well-substantiated explanation of some aspect of the natural world, supported by a body of evidence and capable of making predictions. Unlike laws, theories provide a framework for understanding phenomena rather than simply describing them. The light intensity statement does not offer an explanation; instead, it states a consistent observation, thus distinguishing it from a theory.

An inference is a conclusion drawn from evidence or reasoning rather than from direct observation. While the light intensity relationship could lead to various inferences about light behavior, the statement itself is not an inference but rather a direct observation of a natural law.

A hypothesis is a proposed explanation made on the basis of limited evidence as a starting point for further investigation. The light intensity statement reflects an established fact rather than a testable proposition or prediction, which is what a hypothesis entails.
