3.2 OPTICS

3.2 OPTICS. Optical Telescopes. Astronomers use telescopes to gather more light from astronomical bodies. The larger the telescope, the more light it gathers. Optical telescopes can focus light into an image using either a lens or a mirror. Two main types: refracting, reflecting.

The Lens Equations

The Lens Equations. It is possible to calculate characteristics of images using formulae. You can find: d o = The distance of the object to the lens d i = The distance of the image from the lens h o = The height of the object h i = The height of the image
