A candle is placed exactly between two PARALLEL plane mirrors. How many images of the candle are formed?
A2
B12
CInfinitely many
D6
Answer & Solution
Correct answer: C. Infinitely many
Each mirror produces an image of the candle, and each mirror also produces images of the OTHER mirror's images, ad infinitum. The result is an infinite chain of images receding into the distance — the effect you see between two facing mirrors in a barber shop. Mathematically n = (360°/0°) − 1 → infinity.
