Why did the theory of light change overtime?

A. The theory was too old and needed to be updated

B. new scientists did not agree with the older theory

C. the scientific question changed, so the theory had to change

D. repeated experimentation introduced new discoveries

it is two answers (A and d)

Explanation:

If we keep the same theory of light today we wouldn't be advanced as we are now so yes the old theory had to get updated or plain or replaced with a newer one, D is also correct because if you repeat something you will find out new things from the first time you tried it out.

D. repeated experimentation introduced new discoveries

Explanation:

The theory of light began in antiquity with the Greek philosophers who believed that light was formed by tiny particles that spread in the ambience at high speed, today we know that this is not true, through the realization of innumerable experiments. This theory was believed for years, until through several experiments that took place through the session, it was allowed to make increasingly accurate discoveries about who were able to change this theory several times over time. In fact, through more controlled experiments, this change in light may change again.
