ABCTE -The Solar System and the UniverseTools of the Astronomer - correct answer The basic tool that astronomers use to study celestial objects is the telescope. People tend to be most familiar with optical telescopes, but astronomers use telescopes that span the entire electromagnetic spectrum. Radio Waves - correct answer Radio waves are the longest waves of the electromagnetic spectrum. We use radio waves to broadcast radio, TV, and cellular phone signals. Radio waves are also used to pe...
