How does an image form on lenses?
Images are formed when rays of light meet. If rays are refracted by different amounts as they pass through different parts of the lens, they may be brought to a focus - or meet and pass through one point. This is where the image is formed.
What kind of image is not formed by real light rays?
Virtual image
What is a copy of an object formed by reflected or refracted rays of light?
An image is a copy of an object fromed by reflected (or refracted) rays of light.
What is virtual and real image?
A real image in produced by the actual intersection of the reflected rays . Whereas a virtual image is formed when the reflected rays meet after they are produced backwards.
How many light rays are required to locate the image formed by a lens?
2 is the minimum number of light rays required to locate the image (of a point object) formed by a lens. First find the path of rays after refraction and then their point of intersection gives the location of the image.
An image formed when rays actually meet is called?
When light rays come together, they converge.
When is the image said to be real or virtual image?
An image is called real if the light rays coming from a point(point on object) meet at a point after reflection or refraction. An image is virtual if the light rays do not actually meet after reflection or refraction. These rays appear to come from a point which is the point where we say virtual image is formed.
How are virtual images and real images different?
A virtual image is a copy of an object formed at the location from which the light rays appear to come. Whereas a real image is a copy of an object formed at the point where the light rays actually meet.

Virtual Image
Because the light rays never meet a concave lens can produce?
Because the light rays never meet, a concave lens can produce only a virtual image.
How does a lens create an image?
A lens forms an image when all the rays of light meet in the focal point.
How do you determine virtual and real images?
A virtual image is formed when the reflected rays meet after they are produced backwards. Whereas a real image in produced by the actual intersection of the reflected rays.
