Question

-F.-
a) In which telescope this type of arrangement of lenses are used?
b) Explain in brief the working of this telescope.
c). How different types of magnification is obtained?
8) Draw the diagram and label it.​

Answer 1

Explanation:

1. A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used for long focus camera lenses.
2. A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. ... The bigger the mirrors or lenses, the more light the telescope can gather. Light is then concentrated by the shape of the optics.
3. By convention, for magnifying glasses and optical microscopes, where the size of the object is a linear dimension and the apparent size is an angle, the magnification is the ratio between the apparent (angular) size as seen in the eyepiece and the angular size of the object when placed at the conventional closest
