A converging lens (or convex lens) is curved on both sides. This means the light rays coming out of it come together at a point – they converge.

amount of magnificaton depends on ??
how curved the surface of the lens is - how close the lenses are placed.

A real image ??
image formed where the light rays are focussed.

A virtual image ??
one from which the light rays appear to come but don’t actually come from that image like in a mirror.

refracting telescope ??
A refracting telescope works bending light through a lens so that it forms an image. There are a few problems with refracting telescopes: some of the light reflects off the lens so the image is very faint large lenses are needed to improve the magnif

Reflecting telescopes??
In a reflecting telescope the image is formed by reflection from a curved mirror. It is then magnified by a secondary mirror.
