How telescope works?
Telescope is utilised for magnified pictures of far off items like star, planet, universes. The telescope is without a doubt the most significant analytical device in astrology.
You are in the right place, this post is about the telescope.
We think space is silent and dark but this is not actual. It is impossible to see space empty eyes. If you take a telescope and see the sky then you are able to see stars, galaxies and planets. But how it works?
There are three basic types of telescopes,
1.Refracting telescope
In Refracting telescope, we use 2 lenses one as objective( towards the object ) another as eyepiece (near our eye). Both objective and eyepiece are convex lenses.The light ray from the object falls upon the objective lens. These rays from infinite duration these rays meets at the focus of the objective lens. We place the eyepiece as the focus of both objective and eyepiece is at a single point. As the focus point is same the refracted rays are now in the focus point of eyepiece. Now these refracted rays pass the eyepiece as these rays are from focus we are able to absorb these rays clearly and magnified.
2.Reflecting Telescope
In reflecting telescope we use two mirrors. One is primary another secondary mirror. The primary mirror is located at the bottom of the telescope . When the light ray From the object falls on the first mirror,they reflects and falls on the secondary mirror. Secondary mirror is presented just above the primary mirror. Finally the reflected ray from secondary mirror fall on our eyes and we see it.
3.compund telescope
Compound telescopes are generally called catadioptric telescopes. These kinds of telescopes have both a refractor and reflector. The refractor is used to frame the image. The reflecting is bended and the light skips off of the item. Along these lines it shapes a image. With both of these two components together, it shapes the compound telescope.
From these telescopes we are only able to absorb the visible light. But science progress day by day . Now a days we are able to absorb all types of electromagnetic spectrum from space.
How Radio telescope works?
Radio telescopes are worked in all shapes and sizes dependent on the sort of radio waves they get. In any case, each radio telescope has a receiving wire on amount and in any event one bit of recipient gear to recognize the signals.
Since radio waves are so long and cosmic radio sources are amazingly weak, radio telescopes are the biggest telescopes on the planet, and just the most touchy radio recipients are used inside them. Sadly, these huge receiving wires likewise get radio obstacle from present-day hardware, and incredible effort is taken to shield radio telescopes from radio reproduction impedance. There is an antenna ,which receives the signal and send it to the recorder . As the radio signals are weak we use amplifier.
We use x-ray telescope, infrared telescope and gamma-ray telescope for better results from space.
