Advantages And Disadvantages Of Refracting Telescope

Decent Essays

Introduction: The refracting telescope or the refracting lense inside, is really useful at seeing distant objects, making them appear larger and closer then it actually is, for e.g, it is mostly used for astronomers to look around space, having an eye on most planets.
What happens when the light travels from one medium to the other: The light travels everywhere, hitting everything and at the same time reflecting at a certain angle.. When speed of light is normally being discussed, it is mostly being referred to its maximum speed that it can hit, and that is the speed of light in a vacuum. Having no air or any other mediums, the light has no obstacles, letting it free to go everywhere at its speed, which is 3.00 x 108 m/s. When an medium …show more content…

Especially when wanted to be build in larger size and larger lense. The cost of the refracting telescope runs to about $500 to $2000 per inch of the objective lense.
Another disadvantage is that the refracting telescope don't focus the colours very well because the light just bounces of and creates different colours that are just bending and refracting everywhere,focusing different colours at different points. Makes it really hard to make it to focus and to bring them all together and see the proper colorful picture that is wanted. This is also known as chromatic aberration. This could be solved by using the coated lenses to reduce this problem to the minium.
If the lense is a bit more thicked, most light won't even be able to breach through, as well as not giving in any colours to create the virtual or the real image.

Advantages:
The refracting telescope lense doesn't need much cleaning as they are very well sealed inside its build.
After the first alignment, they are really needed to be re done since they are more resistant to the
