Asked by gspublicschool 5th February 2019 10:12 AM. Real Image We can define a real image as one that is formed when rays of light are directed at a fixed point. But here light from an object is allowed to hit the mirror and when light rays get reflected from the mirror then it looks like the rays are diverging somewhere behind the mirror. For a virtual image, rays from a single source point diverge after they pass through the lens. The key difference between real and virtual images is that the real image is formed by the actual intersection of light rays after reflection or refraction of light, while the virtual images are formed when light rays appear to meet at a point in the area beyond the mirror. A diverging lens or convex mirror is used to produce a virtual image which is diminished in size when compared to the actual size of the object. Privacy, Difference Between Convex and Concave Mirror, Difference Between Convex and Concave Lens, Difference Between Reflection and Refraction, Difference Between Nominal GDP and Real GDP, Difference Between Solar Eclipse and Lunar Eclipse. On the other hand, a virtual image refers to an image produced when the light rays originating from an object only appear to strike at a certain point. No, real images can be either smaller or larger than the object.
