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 telescope has an eyepiece lens and a mirror?
A reflecting telescope has both an eyepiece lens and a mirror. Light enters the telescope and is reflected off the primary mirror to a secondary mirror, which then directs the light to the eyepiece where it is magnified for viewing.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
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 part of a telescope focuses the incoming light?
The objective lens or mirror is the part of a telescope that focuses the incoming light. This lens or mirror gathers the light from a distant object and brings it to a focus at a specific point in the telescope where it can be magnified for viewing.
What type of lens is used for the rear view mirror of car?
usualy concave mirror.
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 mirror is used in a magnifying mirror?
we can use convex lens(having tapered ends) for that. but the magnifying capability depends on the power the lens. A magnifying glass works by creating a magnified virtual image of an object behind the lens. The distance between the lens and the object must be shorter than the focal lenght of the lens for this to occur. Otherwise, the image appears smaller and inverted, and can be used to project images onto surfaces.
Which lens will form exact mirror image?
concave lens will form exact mirror image.
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
Where is the focus located?
The focus is the point at which light rays converge after passing through a lens or reflecting off a mirror. For a concave mirror or converging lens, the focus is in front of the mirror/lens. For a convex mirror or diverging lens, the focus is behind the mirror/lens.
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 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.
Is the normal always drawn at 90 degrees from the mirror and lens?
No, the normal is drawn perpendicular to the surface of the mirror or lens at the point where light rays strike. It is used to determine the angle of incidence and reflection or refraction.
Which mirror is used in solar cooker Concave or convex mirror or concave lens or convex lens?
A concave mirror is used in a solar cooker to concentrate sunlight onto a central point, where the cooking vessel is placed. This focusing of sunlight helps to increase the temperature inside the solar cooker for cooking food.
