Make a picture. Note that the virtual image is on the same side of the lens as the object. And the image distance has to be taken negative, if it is virtual image.barryj said:
A virtual image is an optical phenomenon that occurs when light rays appear to originate from a point behind a mirror or lens, rather than in front of it. It is a type of image that cannot be projected onto a screen or captured on a photographic plate.
A real image is formed when light rays actually converge at a point, allowing the image to be projected onto a screen. A virtual image, on the other hand, appears to originate from a point behind the optical device and cannot be projected.
The calculation of a virtual image is affected by the distance between the object and the mirror or lens, as well as the focal length of the optical device. The size and orientation of the object also play a role in determining the characteristics of the virtual image.
The distance between an object and its virtual image is known as the virtual image distance. It is equal to the distance between the optical device and the point where the light rays appear to originate from. This distance is always positive, indicating that the virtual image is located behind the optical device.
Yes, virtual images can be magnified or reduced in size, just like real images. This is determined by the characteristics of the optical device, such as its focal length and the distance between the object and the device. However, unlike real images, virtual images cannot be projected onto a screen or captured in a photograph.
