Definition

In optics, a negative image distance refers to the distance between the mirror and the virtual image formed by a convex mirror, where the image appears on the same side of the mirror as the object.

Examples

• The convex mirror in the science lab showed a negative image distance, making it appear as if the students were standing behind the mirror.
• In optics, a negative image distance is a common occurrence when using convex mirrors.

Synonyms

• Virtual image distance
• Apparent distance

Antonyms

• Real image distance
• Positive image distance

Additional Information

Convex mirrors are commonly used in optics to reduce the size of an image and create a virtual image. The negative image distance is an important concept in understanding how convex mirrors work. In everyday life, convex mirrors are often used in security systems, such as CCTV cameras, and in rearview mirrors in vehicles.

In physics, the concept of negative image distance is used to calculate the magnification of an image formed by a convex mirror. This is done by using the mirror equation, which relates the object distance, image distance, and focal length of the mirror.

Etymology

The term “negative image distance” is derived from the concept of negative numbers in mathematics, which was developed in ancient India and Greece. The concept of image distance was later developed in the field of optics.

Usage Notes

In optics, the term “negative image distance” is often used to distinguish it from the real image distance, which is the distance between the mirror and the real image formed by a concave mirror.

Cultural References

The concept of negative image distance has been featured in various science fiction movies and TV shows, where characters use convex mirrors to create illusions or deceptions.
