What kind of shape is the primary mirror of a reflecting telescope?
LooneyTunerIan
The name of this type of instrument is derived from the fact that the primary mirror reflects the light back to a focus instead of refracting it. The primary mirror usually has a concave spherical or parabolic shape, and, as it reflects the light, it inverts the image at the focal plane.

What is the purpose of shape of parabolic antenna?
The parabolic shape is a special concave reflecting surface that concentrates wave energy. It is used to collect the parallel waves from an extremely distant source. There is a special location called the focal point where the wave receiver (detector) is placed. Waves arriving from any other direction (angle) will concentrate away from this receiver and are ignored. You can also emit energy at the focal point. The reflected energy will stay concentrated (parallel) over extreme distances.

Why is the primary structure of a protein important in order to carry out its activity especially if this protein has a catalytic activity?
The primary structure of a protein is the sequence of amino acids in each of its chains. (Some proteins have more than one chain.)This sequence determines how each chain coils and turns (the secondary structure), and in turn how the whole molecule folds (the tertiary structure). The correct primary structure is essential for the chain to acquire the correct three-dimensional (3-D) shape.Some amino acids have negative charges on them at physiological pH; some positive. This will influence how different sections of a chain attract and repel one another, and in turn this affects the final shape. Also, one of the amino acids can form sulfur-sulfur cross-links between different parts of the chain. Hydrogen bonding can hold different sections of a chain in position, too, and this will only occur between certain amino acids.If the protein is an enzyme, it has one or more active sites. Each of these has a shape that is complementary to part of the relevant substrate. So the enzyme must have the correct shape if it is to exhibit catalytic activity.
The primary mirror of a reflecting telescope is what kind of shape?
It is a paraboloid, which focusses the light from a star down to a single point which can then be looked at through the eye lens or eyepiece.
Reflecting and refracting telescope what's the difference?
Refracting telescope: Brings light to a focus by passing it completely through a transparent glass lens.The lens must be perfect throughout, and unobstructed.Reflecting telescope: Brings light to a focus by reflecting it from the surface of a curved mirror.The surface shape must be perfect, but the mirror may be made of anything, and can be supportedby anything.
Why you are using parabolic shape for radio telescope?
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.

What shape mirror is used to collect light in a reflecting telescope?
It's definitely concave, and up until recent times, it was always parabolic. Modern optical techniques, bordering in this contributor's view on the black magic, now make it possible to make the mirror's 'figure' spherical, with the resulting ray bundle then 'corrected' by more mirrors of various shapes later down the line.
How does a reflecting telescope are build?
I don't know the manufacturing process, but I know how it's designed. Basically a telescope is just a parabolic reflective surface (a mirror if it's designed to collect visible light). The light comes in through the lens and is "collected" by the parabolic mirror. Because of the shape of the parabola, all the light is reflected to one location, the focus. If it's a digital telescope there is a sensor just beyond that focus, which picks up all the incoming light. Otherwise, the eye piece redirects the light to your eye. This allows you to see objects more clearly because a greater sample of light was taken, then focused down to to a size your eye can see. If you have a 12 inch mirror on the telescope, you'll be seeing what you would see if you had 12 inch wide pupils.
Is concave mirror in shape of parabola?
no concave mirror is in shape of concave mirror
How does a infrared telescope work?
A refracting optical telescope uses two lenses, like magnifying glasses, to gather and focus the light carrying the images of the target that's being observed. The first lens is called the primary lens. It's the larger of two lenses. It's located at the far end of the scope away from the eyepiece where the observer will sight the target. The target's light enters the scope through the primary lens. The Yerkes Observatory in Wisconsin USA is the largest refracting telescope. It's primary lens is a tad over 1 meter in diameter. The eyepiece at the near end is the second lens. It takes that gathered light from the primary lens, and focuses and magnifies it even further. So whatever the target might be is magnified many times over. First by the larger lens and then again by the smaller eyepiece lens. So, for example, if the primary lens magnifies by 5X and the eyepiece does it by 10X, the overall magnification is 50X. The two multiply.
Why is it important to keep temperature of telescope mirror or lens canstant?
It's important to keep a constant temperature because materials expand or contract depending upon how hot they are. Should one region of the telescope become hotter than the rest, it will change it's shape more, and distort the mirror, reducing the clarity of any images.
What does reflecting a shape mean?
A shape that can reflect most of the light back.
How did sir Isaac Newton discover the reflecting telescope?
He was wanking his wife when he saw the stars glitter and looked through a glass block and formed a small shape around his eyes and manged to see inside the stars.
What property of an optical telescope is associated with sharper images?
The aperture of the main lens or mirror, which also determines the light gathering power ------------------------- True but the quality of the mirrors or lenses (how near they are to a perfect shape for the design of telescope) determines the sharpness of the image.
