A device that collects light, magnifies images, and uses mirrors , a device used to see distant objects and show their shape and color up close, used to explore the sky before anything else. Which device collects light and magnifies images? And used? Is it a mirror? We will know this later.
A device that collects light, magnifies images, and uses mirrors
A device that collects light, magnifies images, and uses a mirror to act as a collector to collect visible light or radiation of multiple wavelengths. This device is an astronomical telescopeBecause large astronomical telescopes collect more light than the human eye can, and an instrument attached to the telescope sorts the incoming radiation by wavelength, the blue light can be separated from the red light and the temperature of the star can be easily measured. can be determined, but other times, the observer wants to look at individual spectral lines to determine what something is made of, or to measure its speed, as described in the chapter on radiation and spectra. A telescope contains a type of detector, a device that senses radiation in selected wavelength ranges, after which the observations are permanently recorded.
Components of an Astronomical Telescope
The main parts that make up any astronomical telescope are:
- Primary Lens: It is the main component of the device and the advantage of the lens is that it can collect more light and through it you can see dim objects.
- Primary mirror:It plays the same role as the primary lens in reflecting telescopes.
- A lens that magnifies the image.
- InstallIt supports the tube, allowing the telescope to rotate.
Factors affecting the viewing of objects using an astronomical telescope
Since most telescopes have mirrors or lenses, their light-gathering power can be compared by comparing the apertures or diameters of the aperture through which light passes or is reflected. As the aperture size increases the amount of light the telescope collects increases. A telescope with a 4 meter diameter mirror will collect 16 times as much light as a 1 meter diameter telescope.
At the end of this article, we emphasize the most important points mentioned in it A device that collects light, magnifies images, and uses mirrors In addition, its components and factors influencing the viewing of objects through it were identified.
