Why is a concave mirror better for gathering light than a plane mirror on a telescope?
-- A concave mirror gathers the light and bunches it up all in one place, called
the "focus" of the mirror. There's a "real image" at that place, and you can
capture it with a piece of ground glass, tissue, photo-film, or light-sensitive device
at that place.
-- A plane mirror doesn't gather anything. It just kind of sends the light back
toward where it came from. It doesn't form any real image, and there's nothing
to capture.
What else can I help you with?
What part of a reflecting telescope would you measure to find the apeture?
To find the aperture of a reflecting telescope, you would measure the diameter of the primary mirror. The aperture of a telescope is the diameter of its primary light-gathering element, which in the case of a reflecting telescope, is the primary mirror.
The light gathering power of a telescope increases as the objective increases?
Yes, the light gathering power of a telescope is directly proportional to the surface area of its objective lens or mirror. A larger objective can collect more light, allowing for brighter and clearer images to be observed. This increased light gathering power is beneficial for viewing faint or distant objects in space.
Why inner curved surface is known as Concave mirror?
Inner curved surface is known as concave mirror because inner side of the spherical mirror is polished to reflect the light is called concave mirror,and concave mirror is know because concave mirror converges parallel beam of light.
Which optical instrument uses a large concave mirror a plane mirror and a convex lens to gather light focus and enlarge an image?
Astronomical telescopes use a large concave mirror, a plane mirror, and a convex lens in their design. The concave mirror gathers light, the plane mirror reflects it to a more convenient viewing location, and the convex lens magnifies and focuses the image for observation.
Where you have to be to see an upright image of yourself in concave mirror?
To see an upright image of yourself in a concave mirror you must be closer than the principal focus. Hope this helps.
How is the size of a reflecting telescope indicated?
The size of a reflecting telescope is typically indicated by its aperture, which is the diameter of the primary mirror. Aperture size plays a crucial role in determining the light-gathering ability and resolving power of the telescope.
Is a reflecting telescope cancave or convex?
The telescope is cylindrical. Its primary mirror is concave.
What type of telescopes uses a concave mirror?
A reflecting telescope.
In a reflecting telescope the objective is a?
mirror with a concave parabolic figure
What part of a reflecting telescope form the image?
a concave mirror and an angled plane mirror
In principle the dish of a radio telescope operates in the same manner as the?
Concave mirror of a reflecting telescope
When light strikes the large concave mirror of a reflecting telescope where is the light focused?
In front of the mirror
When light strikes the large concave mirror of a reflecting telescope where is the light focus?
In front of the mirror
What kind of telescope uses a concave mirror?
Concave means bulging inward - reflecting telescopes use this sort of mirror. The first telescope designed to use one was invented by Isaac Newton and they are therefore called "Newtonian" telescopes.
What is the use of reflecting telescope?
a. concave mirror b. a convex lens c. a plane mirror or d. all the above.
What is better a 60mm or a 70mm telescope?
70 mm. The numbers refer to the diameter of the main lens or mirror; the larger this number, the more light-gathering the telescope is, and also, the higher its resolution will be.70 mm.
