Refracting
a refracting telescope or refractor uses Convex lenses and all things considered they are more expensive than reflectors which use concave mirrors or mirror-lenses. there was never a refractor larger than about 36 inches. they are too expensive per inch of caliber.
A reflective telescope uses concave mirrors to focus light
Optical, whether refracting or reflecting.
reflecting telescope. uses a telescope.
it is a telescope
"reflecting"
It's called a reflecting telescope.

The convex lenses can be used in magnifying glasses. They are thicker in the center than in the edges. They are also used in the glasses of those affected with farsightedness. The shape of the lenses used for our eyes is also convex so as to allow it to fit snugly into the eye in shape.
Bias occurs when scientists' expectations change how the results of an experiment are viewed.
b
something that is viewed in 3-d
A coverslip goes on top of a slide to trap the matter being viewed.
Concave mirrors magnify what is viewed in them. That is similar to how convex lenses work (things work opposite with mirrors). So you get a closeup view of your face while you apply makeup.

The Newtonian Telescope.
With a telescope yes.
the scientist viewed the stars with his brand new telescope.
According to scientists, the refracting telescope uses a convex lens which increases the size of an image. The most common use of this telescope is for viewing solar system planets such as Jupiter and Mars.
Reflecting telescopes are designed to have a curved lens which allows for objects further away to be seen clearer. For this reason astronomers and other individuals that study outer space use reflecting telescopes.
By using a Reflective telescope the viewer sees the image of a normal telescope, reflected on a mirror, which is viewed through a microscope, by doing this the telescope doubles it's viewing ability
A reflecting telescope uses a curved mirror to concentrate the light from distant stars, and is a very useful technique. There are very clever techniques and technicians, which can produce a mirror perfect over all its area, to within part of the wavelength of light!! The alternative method of using a glass lens, suffers from various difficulties, such as distortion and loss of light. You do not ordinarily consider focus in an astronomical telescope, for all the stellar objects are essentially at infinity.
Mercury is the most unlikely to be viewed because of its proximity to the sun, but it can be viewed with special equipment, like a light filter. All outer planets can be viewed with a telescope depending on the planets position relative to Earth.
