What does the light gathering ability of a telescope depend on?
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
The light-gathering power of a telescope varies with the of the diameter of the lens or mirror?
Yes, that is correct. A greater main mirror, or main lens, will gather more light.Yes, that is correct. A greater main mirror, or main lens, will gather more light.Yes, that is correct. A greater main mirror, or main lens, will gather more light.Yes, that is correct. A greater main mirror, or main lens, will gather more light.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
What telescope has an eyepiece lens and a mirror?
The telescope described is an optical telescope. If the primary optic is a mirror, it's a reflector, and it the primary optic is a lens, it's a refractor.
How is resolution affected by the size of a telescopes mirror or lens?
The resolution is directly proportional to the diameter of the main mirror or lens. For instance, twice the diameter means twice the resolution.
Which mirror is used in solar cooker Concave or convex mirror or concave lens or convex lens?
convex mirror is not used in solar cooker since it form image inside the polished surface
What type of lens is used for the rear view mirror of car?
usualy concave mirror.
What mirror is used for oil immersion?
100x lens is used with oil immersion
Is lens the same as mirror?
a lens you can see through and a mirror reflects
What are three things that have been used in a microscope?
Lens, light, mirror
What is a difference between concave mirror and concave lens?
A concave mirror is usually used to project something onto a screen. A concave lens is usually used to view an image through the naked eye.
Which lens will form exact mirror image?
concave lens will form exact mirror image.
What does the light gathering ability of a telescope depend on?
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
What is a condenser lens used for?
A Condenser Lens is a device made up of a series of lenses and sometimes a mirror, that is used to gather and 'focus' light to direct it onto an object through a different projection lens.
What is another name for a convex lens?
Concave and convex can refer the types of lenses used to treat refractive errors in the eyes. Concave is another word for myopic lens and convex is another name for a hyperopic lens also known as nearsighted and farsighted respectively
What is the differebetween a lens and a mirror?
a lens will focus the light to a point or will disperse it(concave or convex lens) same as with a mirror, tho lens have a differnce, they are transparent and will let the light rays pass through themand form a real image behind the lens, while a mirror cannot.
What is the function of the convex lens of the eye?
Convex lens- converging lens: lens such that a beam of light passing through it is brought to a point or focus. This type of lens is often used for close examination of samll objects. Examples: manifying glass, small car mirror, 7-eleven mirror
