Virtual image

Definition

A virtual image is an image formed by rays that appear to converge but do not actually meet. It cannot be projected onto a screen because the light rays only seem to come from the image location.

5 Must Know Facts For Your Next Test

1. A virtual image is always upright when formed by a single lens or mirror.
2. Virtual images are formed on the same side of the lens as the object in diverging lenses.
3. The magnification of a virtual image can be greater than, less than, or equal to one.
4. Virtual images cannot be captured directly on physical media, unlike real images.
5. In concave mirrors, virtual images are formed when the object is placed between the focal point and the mirror.

Related terms

Real Image: An image formed by converging light rays that can be displayed on a screen.

Concave Mirror: A mirror with an inward-curving reflective surface that can form both real and virtual images.

Convex Lens: A lens that causes parallel light rays to converge to a focal point, forming both real and virtual images depending on object placement.
