Question

Draw a labelled ray diagram of a refracting telescope. Define its magnifying power and write the expression for it. Write two important limitations of a refracting telescope over a reflecting type telescope.

Answer 2

A repetitive telescope with its magnifying power and writing its own quote and two important repetitive telescope limits on a light telescope is:

• A refracting telescope (also called a refractor) is a type of visual telescope that uses the lens as its target to create an image (also referred to as a dioptric telescope).
• The design of the opposing telescope was originally used for spy glasses and star telescopes but also for long-range camera lenses.
• The ability to magnify a telescope is the measure of the angle obtained from the eye by an image to the angle obtained by the object alone.

Light telescope limitations over light telescope type:

• The display telescope has the problem of chromatic fluctuations as we use large-size lenses.
• The need for large lenses is often very heavy so it is difficult to make and support the edges.
