WebConvex lenses are thicker at the middle. Rays of light that pass through the lens are brought closer together (they converge). A convex lens is a converging lens.. When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.. The distance between the principal focus and the centre of the lens is … WebA virtual image is defined as: An image that is formed when the light rays from an object do not meet but appear to meet behind the lens and cannot be projected onto a screen. A …
Object image and focal distance relationship (proof of formula)
WebA virtual image is formed when light rays are diverging, and so the object appears to be in a different place. For example, when you look into a mirror, you see a virtual image.

A magnifying glass is a convex lens used to make an object appear much larger than it actually is. This works when the object is placed at a distance less than the focal length. The image is: 1. upright 2. magnified 3. virtual Only the person using the magnifying glass can see the image. The image cannot be … See more Cameras and eyes contain convex lenses. For a distant object that is placed more than twice the focal lengthfrom the lens, the image is: 1. inverted 2. diminished 3. real See more Projectors contain convex lenses. For an object placed between one and two focal lengths from the lens, the image is: 1. inverted 2. magnified 3. real In a film or data projector, this image is formed on a screen. Film must be … See more WebThe image is virtual and will be on the same side of the lens as the object. Example 2 An object is placed 3 cm in front of a diverging lens with a focal length of 5 cm.
