real and virtual environments

An image can be real or virtual. A real image is formed when the rays of light actually intersect after reflection. A virtual image is formed when the light rays after reflection do not actually intersect but appear to diverge from it (these rays of lig..

Question: The image produced by a concave lens is ________. 1. always virtual and enlarged 2. always virtual and reduced in size 3. always real 4. sometimes real, sometimes virtual Answer: ..

F is a point on the principal axis of the mirror at which, rays incident on the mirror in a direction parallel to the axis actually meet or appear to diverge after reflection from the mirror. F is a real point in case of concave mirror and F is a virtual point in case of convex..

Question: The image formed by a plane mirror is always _______. 1. real and erect 2. virtual and erect 3. real and inverted 4. virtual and inverted Answer: ..

Question: An object is placed 12 cm from a convex lens whose focal length is 10 cm. The image must be. 1. virtual and enlarged 2. virtual and reduced in size 3. real and reduced in size 4. real and enlarged Answer: ..

For both type of lenses, the height of the object is always positive, while the height of the image may be + or - depending upon its nature. As per sign convention for lenses, the height of an inverted and real image is negative and hence the magnification of a lens is negative when ..
