Answer:
Refracting Telescope
Explanation:
Using a telescope, one may create a magnified view of faraway things. In order to collect and analyze radiation from the gathered data, a telescope is essential. The image shows a refracting telescope in action. Refracting telescopes are essentially optical telescopes that create images using lenses. It is additionally known as a dioptric telescope.
<em>What's the function of a refracting telescope?</em>
In its most basic configuration, a refractor telescope collects light from and creates a picture of what you are attempting to see using a convex lens at "the front" of the telescope, known as the objective lens.
An eyepiece takes up the picture and amplifies it for inspection after the light is bent by the single convex lens at a certain distance.
The drawback of a single convex lens is that not all colors of light are bent equally by it. Consider the way a prism creates a rainbow by dividing a light beam.
At the eyepiece, this uneven light bending creates a colorful picture that, if it's severe enough, becomes undefinable or useless. We refer to this as chromatic aberration.
Hundreds of years ago, humans discovered that making glass with
slightly varied "impurities" in it caused the various varieties of glass to bend light differently from one another.
As a result, the achromatic lens was created. To lessen chromatic aberration, two distinct types of glass are combined in this way. We have been utilizing achromatic lenses for our telescopes for the past 200 years or more.
Going even further, achromatic lenses are enough, or can be, for the majority of astronomers and the observing they undertake, even if they do not provide completely color-free images (that is, images free from chromatic aberration, not a b&w image). Even better refractor telescopes without chromatic aberration were desired by several telescope manufacturers and astronomers. As a result, the apochromatic refractor was created. A well constructed apochromatic refractor will, for all intents and purposes, provide a colorless image.
For the objective lens of the apochromatic refractor, three different kinds of glass are used. Apochromatic lenses can be manufactured from two different types of glass, but whether two or three lens elements are used, at least one of them must be a more expensive, rarer variety of glass. The price of the pricey glass has been decreasing as more is made to match the demand since telescope manufacturers have been making apochromatic refractors for many years. As a result, amateur astronomers may now afford this kind of telescope.
As a result, a refractor telescope contains an objective lens that collects the light and picture of the object you wish to study, and an eyepiece that focuses and amplifies that light and image for observation.
Cheers!
