Investigating energy waves other than light is usually accomplished by using a a. refracting telescope

b. microscope

c. reflecting telescope

d. radio telescope

d. radio telescope

Explanation:

A radio telescope allows the analysis of radio light waves by first, collecting them, then bringing them to a focus and amplifying them in preparation for analysis. They are the largest telescope in the world and are said to have the ability to observe light with long wavelengths. This makes them different from optical telescopes that are meant to observe visible lights. This allows the astronomers to study the composition of the heavenly bodies in the universe.
