What Is A Virtual Image A virtual object is a point where reflected light rays physically meet while a virtual object is a point where the light rays only appear to meet Since at a virtual image there is no physical meeting of rays it cannot be obtained on a screen because to obtain an image on a screen it is necessary that light rays physically meet on the screen
With virtual images you don t usually have this problem with focusing because the image is by definition on the other side of the lens You rarely put your eye that close to the lens and the image is even farther away But if you put the object at 1 cm from the lens the virtual image will also be 1 cm in front of the lens They might actually intersect real image or one might have to geometrically produce them to get them to intersect virtual image One might always find that the real image is formed if this point of intersection is on the reflected refracted side An object is

Another image of your nose is your nose You can see both but the mirror image is virtual because the light from that image does NOT pass through the position inside the wall where the image is The actual object your nose is not a mere image but is a real image Light from the nose actually does come from the position of the nose To see a real image you have to stand at the focal point but you can view virtual images from different angles NB a real image would be formed on our retina but the eye is more like a camera and the screen is in the optic centre at the back of our brain This is where the images we see are created We see a virtual image of our surroundings
Virtual image is formed when the diverging rays appear to meet if they are projected backwards In a real image the rays converge so if a screen is put at the point at which the rays converge then the image can be vied on the screen Our eyes have a convex lens which converges light rays Correct The only way to experimentally determine the position of a virtual image is to convert it to a real image and calculate where the virtual image was This is simpler than you probably think For example if you can see the virtual image that means the lens in your eye is focussing the image onto your retina

I am trying to learn about optics and I am having a hard time understanding the meaning of real vs virtual image My understanding is that for a concave mirror the image focuses on the same side as the object so it is a real image For a convex mirror the image focuses on the opposite side of the object from the mirror so it is a virtual For example if there is real image behind a lens putting a white screen on that location will show the image A virtual image is an image because it is obtained the same way but virtual in the sense that putting a white screen on the location will show no image Hence the term virtual image This definition is very physical
