alleryRadio waves are produced by accelerated charges in:
AInner shell orbits
BHot molecules
CConducting wires
DAtomic nuclei
Answer & Solution
Correct answer: C. Conducting wires
1. Different parts of the spectrum come from different sources.
2. Radio waves come from currents oscillating in an aerial.
3. That is accelerated motion of charges in conducting wires.
4. So the answer is conducting wires.
