Questions asked by the same visitor
The shadow produced by an object held close to a piece of paper in sunlight will be A. sharp. B. fuzzy. User: What is the ultimate source of electromagnetic waves? A. Vibrating atoms B. Vibrating molecules C. Radio sets D. Vibrating charged particles E. TV antennas
Weegy: The answer is letter D The frequency of the wave is proportional to the magnitude of the particle's energy. Moreover, because photons are emitted and absorbed by charged particles, they act as transporters of energy. [ The energy per photon can be calculated by Planck's equation. ] (More)
