a light-collecting area equivalent to that of a much larger telescope.an angular resolution equivalent to that of a much larger telescope.both the light-collecting area and angular resolution of a much larger telescope.Correct
answer: an anguar resolution equivalent to that of a much larger telescope. ;-)
Concave means bulging inward - reflecting telescopes use this sort of mirror. The first telescope designed to use one was invented by Isaac Newton and they are therefore called "Newtonian" telescopes.

The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.
I believe a new management consulting firm, Alodia Consulting, uses it to describe the results they achieve with clients.
I believe you are confusing two things here; there is no such thing as a "heliocentric model of telescope". There is a heliocentric model of our Solar System, and there are telescopes. The two are unrelated.
Interferometry is a technique that uses the interference of waves to make precise measurements of various quantities, such as distance or wavelength. It is commonly used in astronomy to combine signals from multiple telescopes to create high-resolution images. Interferometry is also used in fields such as geology, physics, and engineering for measuring small distances and detecting small changes.
Interferometry is a technique used in physics and astronomy to superimpose and analyze multiple waves of light or radio waves to extract information about the sources or objects they originated from. By measuring the interference patterns created when the waves combine, interferometry allows for high-resolution imaging and precise measurements in a variety of scientific fields.

No, digital telescopes don't exist. The telescope which we know are optical telescopes and what NASA uses are radiation based telescopes, or something related to radioactivity. As far I know, I've never heard about digital telescopes.
A reflecting telescope.
Interferometry is a measurement technique that uses the interference of waves to extract information about a target. In imaging, it can increase resolution by combining signals from multiple detectors. Interferometry enables the production of high-resolution images by eliminating optical aberrations and enhancing contrast.
Most modern telescopes are reflecting telescopes because reflecting telescopes are generally more cost-effective and easier to build at larger sizes compared to refracting telescopes. Reflecting telescopes also suffer less from chromatic aberration and can have a simpler design with fewer optical elements.
It is an observatory.
all telescopes use a mirror.
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
An observatory is the name of a place that uses telescopes and other scientific equipment to study space and astronomy. The Mount Polamar Observitory in the west of the US is an iconic example. Today, Earth based observitories are supplimented by space telescopes.
