Faahfaahinta casharka
Natiijada casharka
I can describe uses of convex lenses and draw scale ray diagrams to determine the position and magnification of an image.
Muuji qoraalka
In cameras and the human eye, the required image distance < the object distance so the image is diminished and inverted.
In projectors, the required image distance > the object distance so the image is magnified and inverted.
A ray incident on a convex lens parallel to the principal axis is refracted to pass through principal focus.
A ray incident on the centre of a convex lens is not refracted.
A ray incident on a convex lens from the principal focus is refracted so it becomes parallel to the principal axis.
