Virtual image
Definition
A virtual image is an optical illusion created by the apparent intersection of light rays that do not actually converge. It is formed when light rays diverge after reflecting or refracting, giving the impression that the image is located behind a mirror or lens.
Analogy
Imagine standing in front of a mirror and seeing your reflection. Now imagine standing in front of a holographic display and seeing a 3D object floating in mid-air. The holographic object is like a virtual image because it appears to be there, but you can't physically touch it.
Related terms
Real image: A real image is formed when light rays actually converge at a specific point, creating an actual image that can be projected onto a screen.
Concave mirror: A concave mirror curves inward and can form both real and virtual images depending on the position of the object relative to the focal point.
Convex mirror: A convex mirror curves outward and always forms virtual images that are smaller than the actual object.
