Answer» There are two basic types of telescopes: reflecting telescopes and refracting telescopes. A reflecting telescope is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image.Refracting telescope is a telescope which uses a converging lens to collect the light. An optical instrument is a device that either processes light waves to enhance an image for viewing, or analyzes light waves to determine one of a number of characteristic properties. |
