Correct answer: D. Resonance

  • A. Refraction
  • B. Frequency Modulation
  • C. Stationary waves
  • D. Resonance

Explanation

When we tune to different stations, we actually change the frequency of carrier wave at which our system will resonate at. Carrier wave is the wave which brings in the information for a given station.

About Scientific Reasoning

Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.
