Reflecting Telescope
A reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.
What else can I help you with?
What is difference between lens and mirror with table?
A lens is an optical device that refracts light to form an image, while a mirror is an optical device that reflects light to form an image. A lens uses refraction to bend light rays, while a mirror uses reflection to change the direction of light rays. Both lenses and mirrors can be used to focus light and form images.
Does the focal length of a spherical mirror or lens change when placed under water?
i do not think so because a mirror an a lens is two same things except that mirrors can reflect the water and the lens may refract or bend the water so that can change the focal length between the mirror and the 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
How is the image formed by a concave lens similar to the image formed by a convex mirror?
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
Is a convex lens more like a convex mirror or a concave mirror in the way it produces images?
A convex lens is more like a concave mirror in the way it produces images. A convex lens converges light rays to form real or virtual images, much like how a concave mirror can do the same by reflecting light. Both convex lenses and concave mirrors can produce both real and virtual images depending on the object's position relative to the lens or mirror.
How are reflecting and retracting telescopes different?
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
What are two uses for a convex lens?
Concave lenses are used in glasses for people who are near-sighted. Convex lenses are used in glasses for people who are far-sighted.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
What is difference between lens and mirror with table?
A lens is an optical device that refracts light to form an image, while a mirror is an optical device that reflects light to form an image. A lens uses refraction to bend light rays, while a mirror uses reflection to change the direction of light rays. Both lenses and mirrors can be used to focus light and form images.
Is lens the same as mirror?
a lens you can see through and a mirror reflects
List two uses for concave lens?
Both concave and convex lenses are used in glasses; A microscope, like a reflecting telescope, uses a concave mirror, a plane mirror, and a convex lens; A refracting telescope uses two convex lenses to magnify images in the sky; binoculars use concave lenses to improve detail.
Does the focal length of a spherical mirror or lens change when placed under water?
i do not think so because a mirror an a lens is two same things except that mirrors can reflect the water and the lens may refract or bend the water so that can change the focal length between the mirror and the lens
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.
What uses a lens and two mirrors?
Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.
What type of telescope uses two lenses?
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
Which lens will form exact mirror image?
concave lens will form exact mirror image.
Why has a lens two focal points but a mirror only one?
because visible light is only emitted from one side of a mirror.
