Real Image and Virtual Image Differences in Physics Import Concepts Must to Know

Question. Difference Between Real Image and Virtual Image.

Answer:

Real Image

  • A compilation of focus points of light rays emitting from an object defined as an image in terms of optics. An assortment of focus points made by the converging rays is known as a real image, whereas the collection of focus points made by the extension of diverging rays is known as the virtual image. In simplistic terms, an image located in the plane of convergence for the light rays emitted from an object known as a real image.
  • When rays converge, real image occurs, and when rays only appear to diverge, virtual image occurs. By usage of concave mirrors and converging lenses, a real image can be produced, but on the condition that the object is placed further away from the mirror/lens than the focal point, and the real image is inverted.
  • As the object nears the focal point, the image will move towards infinity, and when the object surpasses the focal point, the image becomes virtual and is upright. Space is not the same as from the object to the lenses.
  • When the light rays after refraction or reflection meet at a point, it exists in reality, meaning a real image can be placed on the screen. The backward extension of refracted or reflected light rays is true for a virtual image; that is, it doesnีšt exist in reality.
  • For a convex lens, placing an object at or near a distance equal to or less than the focal length will give you a real image. This is similar to what you would get in the case of a concave mirror except for the object placed at a distance equal to or less than the focal point; you will get a real image.

Virtual Image

  • A range of focus points formed by the converging rays is known as a real image, while the collection of focus points made by the extension of diverging rays is known as the virtual image.
  • A virtual image is formed by tracing real rays that arise from an optical device like a mirror or lens, backward to apparent origins of ray divergences. In the diagram of the optical system, the dotted lines represent the conventional virtual ray.
  • Since the rays donีšt converge, a virtual image cannot be created on a screen, but a real image can be produced on a screen as the rays converge on a real location.
  • People can see the image as a real image can be projected onto a diffusely reflecting screen (the image on the screenplays as an object to be imaged by human eyes) .

Differentiating PropertyReal ImageVirtual Image
DefinitionThe real image is the image, which forms when the light rays meet at a particular point after reflection from the mirror.The image, which forms when the light rays appear to meet at a definite point, after reflection from the mirror, is termed as a virtual image.
Interaction of light raysRays actually converge.Rays perceived to converge.
Image formedThe image formed is inverted.The image formed is upright or erect.
Lens usedConverging Lens.Diverging Lens.

Image receptionWe can obtain a real image on a screen.We cannot obtain a virtual image on the screen. In fact, the Image appears to be on the mirror or lens itself.
