A real image is formed when light rays converge and can be projected onto a screen.
How does a real image differ from a virtual image?
How does a real image differ from a virtual image?
A real image can be displayed on a screen, while a virtual image cannot be projected as it appears to come from a location behind the mirror or lens.

Study Notes
Real Image in Optics
- A real image is formed when light rays converge after reflecting off a surface or passing through a lens.
- This image appears in front of the optical device, meaning it can be projected onto a screen or surface.
Difference Between Real and Virtual Images
- Real images can be projected onto a screen, while virtual images cannot; virtual images appear to be located behind the mirror or lens.
- Real images are formed by the actual convergence of light rays whereas virtual images are formed by the apparent divergence of light rays.
Formation Location of Real Images
- A real image is located on the opposite side of the optical device from the object.
- The distance from the image to the lens or mirror varies based on the object's distance and the focal length of the device.
Inversion of Real Images
- Real images are typically inverted compared to the object.
- The inversion occurs when the object is positioned outside the focal length of a converging lens or a concave mirror.
Mirrors that Produce Real Images
- Concave mirrors can produce real images when the object is placed outside the focal point.
- Convex mirrors cannot produce real images; they always produce virtual images due to the way light diverges.
