In a world where mirrors do not reflect visible light but instead reflect sound with perfect clarity, Naledi is standing facing a large flat mirror. She is equidistant from both Keiji, who is silently reading a book to her right, and Priya, who is ringing a bell to her left. What does Naledi perceive coming from the mirror? Respond very briefly.
Given that mirrors reflect sound instead of light in this world, Naledi, facing the mirror, would hear the sound of Priya's bell coming from the direction of the mirror. Since sound is being reflected, the bell's ringing would travel to the mirror, reflect off the surface, and then reach Naledi's ears, giving her the perception that the sound is emanating from the mirror. Keiji is silently reading a book and not making any sound, so there is no sound coming from his direction to be reflected by the mirror. Therefore, the only audible noise that Naledi would hear from the mirror would be the reflected sound of Priya's bell.
