A candle C sits between two parallel mirrors, a distance 0.2d from mirror 1.Here d is the distance between the mirrors.Multiple images of the candle appear in both mirrors.How far behind mirror 1 are the nearest three images of the candle in that mirror?
The passenger-side rear view mirror on a car says, "Objects in the mirror may be closer than they appear".Assuming the images are not inverted, this mirror must be:
