Question

Quizplus · Accepted Answer

Techniques A, B, and C involve analyzing the electromagnetic spectrum (visible light, radio waves, and colors) to infer properties about the particles, including their size. Technique D, measuring the orbital periods of the particles, does not directly provide information about the size of the particles but rather their motion and distribution around Saturn.
