Question

A scientist asks the question: "How fast can light travel?" Why is this a good

Answer 1

This question “How fast can light travel” is considered as an good scientific question because it helps inform for other experiment.

Answer: Option D

Explanation:

The speed of light is a universal physical constant and it is found to be $3 \times 10^{6} \mathrm{m} / \mathrm{s}$ and it is important to determine various physical units such as electromagnetic wave propagation, e.g., optics, radio waves.

This light constant is majorly used in many of the experiments and hence it is very much helpful in determining values required in an experiment.  Thus the measurement of the light speed can help us inform other experiments, so we can conclude option D as correct answer.
