What sentence has the word stargazer in it?
He was a stargazer so he bought a telescope. An amateur astronomer could be described as being a stargazer.
What are the advantages of an earth based telescope?
That means that the telescope is on planet Earth, as opposed to a planet in outer space, like the Hubble Telescope, the Planck Telescope, the Chandra Telescope, etc.It is a telescope based on our earth
Who was the first person to discover Jupiter?
The invention of the telescope is credited to Hans Lippershey. Crude telescopes and spyglasses may have been created much earlier by Dutch opticians, but Lippershey is believed to be the first to apply for a patent for his design. His telescope was made up of one convex lens and one concave lens.Galileo Galilei perfected it by using two convex lenses. He constructed his first telescope in 1609. This telescope is called the Galilean telescope or the refracting telescope.Isaac Newton invented a telescope which used two mirrors. He constructed his first telescope in 1669. His version of the telescope was called the Newtonian telescope or the reflecting telescope.
Why do the sun and moon appear to be the same size when viewed from earth?
no actually the moon is larger than the sun when being viewed especially when the moon is at its full or full moon because it is much nearer to us than the sun.
Why was the moons of Jupiter named after Galileo?
The four largest moons - were named as a group after Galileo because of him being the first person to obseve them through his own invention - the telescope.
Which type of telescope uses a convex lens to increase the size of the image being viewed?
refracting
Which type of telescope uses concave mirrors to increase the size of the image being viewed?
Refracting
What is the lens?
the lens or system of lenses in a telescope or microscope that is nearest the object being viewed
What is object lens?
the lens or system of lenses in a telescope or microscope that is nearest the object being viewed
What uses mirrors to focus light from the object being viewed a refracting telescope or a reflecting telescope?
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.
What types of images are produced by a concave mirror?
A concave mirror is dished in ward. A convex mirror domed. Both images will be distorted in size from actuality. A convex mirror will give a wider view of what you are looking at in the mirror. A concave mirror will compress and magnify the image being viewed.
Where should an object be placed in front of a convex lens to get a real image of the size of the objects?
The image seen through a convex lens will appear upright and enlarged when the object being viewed is within the focal length of the lens.
One function of a refracting telescope?
The nominal function of any telescope is to enlarge the image of a distant object and that is the same for reflecting or refracting or hybrid telescopes. That said, it is a better description of a telescope to say it is a light collector that brings into an image (on the eye or photo sensor of the user) the light that is given off by some distant object. The aperture of a telescope is much much larger than the aperture (iris) of the human eye, so whatever object is being viewed is producing light an a much greater quantity of light is entering the telescope than would be entering the eye. More light allows the image being viewed to be enlarged and still visible to the human eye.
What telescope collects light with a mirror?
The type of telescope is called a reflector. There are multiple subtypes of reflectors like a dobsonian, newtonian, RC, etc. Check out my youtube video on how to work with pictures taken from a telescope. youtu.be/M7-vLeVhM9g
What kind of telescope uses both a reflecting mirror and a refracting lens to produce wide angle photos of the sky?
A reflecting telescope has both magnifying mirrors and lenses to focus the image on the eyepiece. A refracting telescope uses only lenses to magnify and focus. A reflecting telescope can be much smaller, because the light can travel through the barrel of the telescope several times, being magnified with each reflection. This is why most large modern telescopes are reflectors.
What makes a telescope more powerful?
Several factors contribute to the power of a telescope. The size of the objective or primary mirror is a crucial factor, as a larger diameter allows the telescope to capture more light. The quality of the optics and the level of precision in their construction also affect the power of a telescope. Additionally, the type and quality of the eyepiece used can further enhance the power by magnifying the image.
Why the street light refelector are convex in nature?
this is because convex surfaces , being curved outside, have a wider field area. Car rear view mirrors are also a good example of this. In these, convex mirrors are used. This is because, convex mirrors, being curved outside, have a wider field area and show the image of a larger area
