From that, I don't see how I could determine if a virtual image is curved. Real pictures are images generated by the converging of light rays at a spot after they have been reflected or refracted by a mirror or lens while A virtual. However, all of the lens examples I've found show 2 dimensional - if the image flipped, where it's located, and it's magnification. Everything I have read states the camera focuses on a virtual image that and that the virtual image is curved. In case I'm not asking the right questions, the very specific use case that I'm trying to understand is a camera in a underwater housing, looking out a curved glass port into water. I assume that a virtual image from a mirror, will remain the same proportion to the object, but if a virtual image is formed from a lens, does it become "curved"? I am not sure what it means for a camera to focus on a virtual image though. I understand that I can photograph a virtual image because a real image is eventually formed on the sensor. What is the "shape" or apparent shape, of a virtual image? I 'think' I understand the distinction clearly, however, there is one thing that I can't quite wrap my head around. This is not a sign “convention” it is just a statement of fact, or an explanation of what are meant by “real object”, virtual object”, “real image” or “virtual image”.There are a lot of posts regarding real vs virtual images. You will see that light converges to a real image or to a virtual object, and light diverges from a real object or from a virtual image. The lens bends the light, which eventually comes to a focus at a real image, I. However, as far as the concave lens of Figure II.3 is concerned, the point O to which the light was converging before it reached the lens is a virtual object. It is converging to the point O, and, if the concave lens had not got in the way, it would have formed a real image at O. Virtual images are made by rays that do not. Let us look at more differences between real images and virtual images in this article. Light is coming from the left – perhaps from a big lens beyond the left hand edge of the paper (or your computer screen). Examples of real images are those made by a camera lens on film or a projection lens on a motion-picture screen. A real image is formed when rays converge, whereas a virtual image occurs when rays only appear to diverge. Difference Between Real and Virtual image 1, It is formed when the light rays starting from an object meet after reflection or refraction. 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. The reason that you can see a real image with your eye is that the additional optics of your eye bends the diverging light from the virtual image and makes it converge on to a real image on your retina.įigure II.4 illustrates what is meant by a virtual object. Whereas you can project a real image on to a piece of card or a photographic film, you cannot do this with a virtual image. The light is diverging from a virtual image. After refraction through the lens, the light is diverging from a point where the photons have never visited. As before, light diverges from the real object, but no light converges to a real image. Real photons of light depart from a real object, and real photons of light arrive at a real image.įigure II.3 shows a lens forming a virtual image of a real object. A real image is formed when the light rays actually meet after reflection or. Light diverges from a real object and it converges to a real image. Step 1: First, we need to understand what real and virtual images are. A virtual object, however, may take one by surprise – so let’s look at all of them hereįigure II.2 shows a lens forming a real image of a real object, and I think it requires little explanation. Most people have no trouble understanding what a real object is or the distinction between a real image and a virtual image. 0:00 / 6:33 Real and Virtual Image Physics Najam Academy 343K subscribers Join Subscribe 499 Save 29K views 1 year ago physics realimage virtualimage This lecture is about real.
