what is a virtual image?
a reflected optical image (as seen in a plane mirror)
It is an image that is upright and appears on the opposite side of the mirror from the source object. Rays from the object that are reflected by the mirror appear to come from the virtual image, although they never enter that space. The image you see in a plane mirror is a virtual image, but there are others, such as the image formed by a convex "wide angle" mirror
A virtual image is an optical phenomenon in which light rays do not actually converge at a point; instead, they appear to diverge from a particular location when extended backward. Unlike a real image, a virtual image cannot be captured on a screen or projected onto a surface. It is formed by the apparent intersection of rays of light that appear to diverge from a certain point.
In terms of getting a deeper understanding of virtual images, it is helpful to understand the concept of reflection and the behavior of light rays. When light hits a mirrored surface or passes through a lens, it can be reflected or refracted, respectively.
To understand the formation of a virtual image, you can follow these steps:
1. Identify the reflective or refractive surface: A virtual image is typically formed by reflection in a mirror or by the refraction of light passing through a lens.
2. Trace the light rays: Imagine or draw light rays originating from an object and reaching the reflective or refractive surface. Draw at least two rays, and remember that they will obey the laws of reflection or refraction.
3. Determine apparent path of rays: Observe the apparent path of the rays after reflection or refraction. Note that in a virtual image, the rays do not actually converge but appear to diverge.
4. Locate the virtual image: Extend the refracted or reflected rays behind the surface of the mirror or lens. The virtual image appears where these extended rays seem to intersect or originate.
It is important to note that a virtual image is formed when the incident rays do not actually converge, which means they won't meet at a common point on the opposite side of the lens or mirror.
Understanding the behavior of light rays, the laws of reflection, and refraction will provide a clearer grasp of the concept of virtual images.
