Faahfaahinta casharka
Natiijada casharka
I can describe the formation of virtual images by convex and concave lenses and draw ray diagrams to find the position and magnification of the image.
Muuji qoraalka
When rays of light are brought to a focus a real image forms. A real image can be projected onto a screen.
Virtual images occur at points where rays appear to (but do not actually) originate from. They cannot form on a screen.
The size and position of a virtual image is found by drawing virtual rays to find where rays appear to originate from.
Upright virtual images are produced by concave lenses, and objects within a focal length of a convex lens.
Convex lenses fix long sight by shortening the focus. Concave lenses fix short sight by lengthening the focus.
