Sound is to echo as light is to reflection. Explanation:
- An echo is produced when sound waves bounce off a distant surface and return to the listener, creating a delayed repetition of the original sound.
- Similarly, light can bounce off surfaces and return to the observer as a reflected image or light, which is called reflection.
Thus, the analogy matches: sound relates to its echoed repetition (echo), just as light relates to its reflected image (reflection).
