Ascientist asks the question: "how fast can light travel? " why is this a good
scientific question?
a. the speed of light can be measured over and over again.
o
b. the speed of light limits the speed of human communication.
c. the speed of light is a fundamental constant in the universe.
d. the speed of light inform other experiments.

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

Option D

Explanation:

The speed of light is a universal physical constant and it is found to be 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.
