A parabolic shape is used for all reflecting collectors ... visible light telescope,
radio telescope, satellite receiver, etc. A parabolic reflector directs all parallel
incoming rays toward one point, called the 'focus' of the parabola.
Usually, by using your eye sight, optical telescope, or radio telescope.
No.
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.
Lots of things are not true about it. Here's one: Corn can not be popped using a radio telescope.
Parabolic mirrors are formed in a dish like shape, the purpose of it's shape is to transmit the electromagnet waves. For example when using a microwave or watching a television, it is through electromagnet radiation that make it possible to function. Television receives the signals via the satellite dish, the satellite dish acts as the parabolic mirror.
Radio Telescope
No, a radio telescope is designed to detect radio waves, which have much longer wavelengths than visible light. Visible light cannot be studied using a radio telescope as it operates in a different part of the electromagnetic spectrum. To study visible light, astronomers typically use optical telescopes.
A parabolic mirror is shaped such that parallel incident light is reflected to a point called the focus. You will have to establish the size required, and the shape. There is an entry in Wikipedia on Parabola, giving the algebra.
Karl Jansky first discovered astronomical radio sources, but I believe it was Grote Reber who first mapped the radio emissions of the sky using a radio telescope in his backyard.
Satellite dishes and radio telescopes use parabolic reflectors, a type of conic section, to collect and focus signals. The lenses in cameras and the shape of headlights in cars may be based on conic sections such as ellipses or hyperbolas for optimal focusing. Roller coasters and water slides often incorporate parabolic shapes in their designs to create thrilling and smooth rides. Many bridges and arches are designed using parabolic shapes to distribute weight efficiently and provide stability. Solar panels are often mounted on parabolic troughs to focus sunlight and generate energy. The shape of a basketball's arc when shot is a parabolic curve. The design of many famous architecture and art pieces, such as the Gateway Arch in St. Louis, is based on conic sections. Landscapers may use hyperbolic shapes in the design of paths or tree lines in gardens. Astronomy uses conic sections to model the orbits of celestial bodies. The shape of the curve for a water fountain is often based on a parabolic function to create an aesthetically pleasing display.
Galileo discovered stars by using the telescope?
The Amazon River was not discovered by Galileo using a telescope.
