Real images are formed by the actual convergence of light rays and can be projected onto a screen, while virtual images are formed by the apparent divergence of light rays and cannot be projected. Wikipedia: A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. In conclusion, the key difference between real and virtual images is how they are formed and projected. Virtual image: The image seen in a flat mirror is an example of a virtual image as the light rays appear to diverge from a point behind the mirror. Real image: The image of a candle formed by a convex lens is an example of a real image as the light rays converge to form the image.Ģ. Size: A real image is usually smaller than the object, while a virtual image is usually the same size or larger than the object.ġ. Distance: A real image is located at a specific distance from the lens or mirror, while a virtual image is located behind the lens or mirror.ĥ. Inversion: A real image is always inverted, while a virtual image is always upright.Ĥ. Projection: A real image can be projected onto a screen or surface, while a virtual image cannot be projected.ģ. Formation: A real image is formed by the actual convergence of light rays, while a virtual image is formed by the apparent divergence of light rays.Ģ. The position of a virtual image can be determined by tracing the path of the light rays back to where they appear to come from.ġ. In daily life when we see the image of our face formed by a plane mirror cannot be obtained. It is a type of image that cannot be projected onto a screen, and it is always upright. A virtual image is seen only by looking into a the mirror or a lens. The position of a real image can be determined by tracing the path of the light rays through the lens or mirror.Ī virtual image is formed when the light rays coming from an object appear to diverge from a point behind the mirror or lens. A real image is formed when the light rays actually meet after reflection or. It is a type of image that can be projected onto a screen, and it is always inverted. Step 1: First, we need to understand what real and virtual images are. cm, diopters, an object distance of o cm cm. Enter data below, then click on the quantity you wish to calculate in the active formula above. Such images are formed with the simple magnifier. Using the common form of the lens equation, i is negative. The linear magnification relationship allows you to predict the size of the image.A real image is formed when the light rays coming from an object converge at a point after passing through a lens or a mirror. Converging lenses form virtual images if the object distance is shorter than the focal length. The lens equation can be used to calculate the image distance for either real or virtual images and for either positive on negative lenses. If a calculation yields a negative focal length, then the lens is a diverging lens rather than the converging lens in the illustration. If an object distance smaller than the focal length is entered to agree with the illustration, then the image is an enlarged virtual image on the same side of the lens as the object and will give a negative image distance. For a lens of focal length f = cm,Ĭorresponding to lens power P = diopters, When the object is inside the focal point the image becomes virtual and. Real & Virtual Images In the above diagram, the image is: Real: the light rays meet each other after refraction In this case, the image is: Virtual: the light. Such images are formed with the simple magnifier. As long as the object is outside of the focal point the image is real and inverted. Jeremy Tatum University of Victoria Most people have no trouble understanding what a real object is or the distinction between a real image and a virtual image. A converging lens has a focal length of 10.0 cm. Using the common form of the lens equation, i is negative. Transcribed image text: Explain the difference between a real image and a virtual image. Converging lenses form virtual images if the object distance is shorter than the focal length.
