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.
How are Canadians viewed throughout the world?
Canadians are viewed as being very polite and in some cases even suck ups. But being a Canadian myself that isn't completely true. It depends on the person.
What are the knowledges of Hera the goddess?
The Greeks viewed their gods and goddesses as being all powerful and all seeing. So... she knew everything.
Why secondary terminal voltage decreases with increase in load?
An increase in load (equivalent to a decrease in resistance*) causes an increase in load current. This increases the internal voltage drop within the transformer, and the terminal voltage reduces accordingly.[*An increase in load means more current is being drawn by that load, so an increase in load is equivalent to a decrease in load resistance]
What are the advantages and disadvantages of ground based telescope?
a normal telescope can be projected further then a space telescope because it is bigger and more of it a space telescope in in space which lets it see further into space and is more exspensive to make ect
Which type of telescope uses concave mirrors to increase the size of the image being viewed?
Refracting
What is object lens?
the lens or system of lenses in a telescope or microscope that is nearest the object being viewed
How factors affect the magnification of a convex lens?
The magnification of a convex lens depends on its focal length and the object distance from the lens. Increasing the focal length or decreasing the object distance will usually increase the magnification. The magnification is also affected by the size of the object being viewed and the optical properties of the lens itself.
How does convex lens affect the area seen?
A convex lens will magnify objects viewed through it, making them appear larger. The lens focuses light rays onto a point, creating an enlarged image. As a result, the area seen through a convex lens will appear larger than the actual object being viewed.
The image produced by a convex lens depends on what?
The image depends on the distance the object is from the lens.
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.
The image produced by a convex lens depends upon?
The image produced by a convex lens depends upon the object distance from the lens, the focal length of the lens, and the type of object being viewed (real or virtual). The characteristics of the image, such as its size, orientation, and location, are determined by the lens formula and the properties of the convex lens.
How does a convex telescope work to magnify distant objects?
A convex telescope uses a converging lens to gather and focus light from distant objects. This lens bends the light rays towards a focal point, creating a magnified image that can be viewed through the eyepiece.
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.
How many lenses do binoculars have?
It depends on the type of reflecting telescope.
What telescope collects light with a mirror?
A reflector telescope collects light with a mirror. The mirror is located at the back of the telescope and reflects the incoming light to a focal point where it is then collected by an eyepiece for viewing.
How does the lens of a light microscope work a. Each concave lens bends light to make the object appear larger. b. Each convex lens bends light to make the object appear larger. c. Each convex lens be?
b. Each convex lens bends light to make the object appear larger. The convex lens in a light microscope refracts and converges light rays to magnify the specimen being observed. By bending light, the lens creates an enlarged virtual image of the specimen that can be viewed by the observer.
