- Two mirrors
- A tomato or any other object
Place two mirrors on a table face to face situated one foot (30cm) apart. Place a tomato halfway among the
mirrors. The tomato's images form endless reflections in the mirrors.
The question is: If you bring the tomato closer to one of the mirrors, will the two closest images come nearer,
further away, or remain in the same place? Try to figure out the answer to this.
HOW DOES IT WORK?
It does not matter where the apple is placed between two mirrors, the two closest images will have be two
feet apart- For instance, if the apple is moved to a position which is one inch (2.5 cm) from one mirror, its
image in that mirror will be two inches (5 cm) from the apple. Its image in the other mirror will be 22 inches (55
cm) from the apple. The point is 22 plus 2 equals 24 inches or two feet (60cm).
