Wavelength correct answers Horizontal distance between the crests or between the troughs of two adjacent waves Photon correct answers quantum of electromagnetic energy; carries an amount of energy that depends inversely on its wavelength Electromagnetic Radiation correct answers changing electric and magnetic fields that travel through ...

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...
