Question 58

This statement is a scientific law.

This statement describes a consistent relationship between the distance of a light source and its intensity, which adheres to the principles of physics. Thus, it qualifies as a scientific law that can be universally applied in this context.

A) law

This option is correct because the statement describes a fundamental principle of light intensity and distance, which is consistently observed in experiments. A scientific law summarizes the results of many observations and experiments and is generally accepted as a fact in science.

B) theory

This option is incorrect as a theory is a well-substantiated explanation of an aspect of the natural world, based on a body of evidence. The statement in question does not provide an explanation but rather a consistent observation regarding light intensity.

C) Inference

This option is incorrect because an inference is a conclusion drawn from evidence or reasoning rather than direct observation. The statement does not require interpretation; it directly reports an observed relationship.

D) Hypothesis

This option is incorrect since a hypothesis is a proposed explanation made on the basis of limited evidence as a starting point for further investigation. The statement reflects established knowledge rather than a preliminary idea awaiting testing.

Conclusion

The statement is definitively identified as a scientific law because it articulates a reliable relationship established through repeated experimentation. Other options, such as theory, inference, and hypothesis, do not accurately represent the nature of the statement, which provides a clear and testable principle rather than an explanation or assumption.
