What is the full meaning of telescope?
1 : a usually tubular optical instrument for viewing distant objects by means of the refraction of light rays through a lens or the reflection of light rays by a concave mirror — compare reflector, refractor. 2 : any of various tubular magnifying optical instruments. 3 : radio telescope.
What is the root word of microscope?
First used in the 1650s, microscope is descended from the Modern Latin microscopium, meaning “an instrument for viewing what is small.” In science, microscopes are essential for examining material that can’t be seen with the naked eye, like bacteria and viruses.
What reflecting telescope means?
A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives.
What is a telescope child definition?
definition: an instrument that uses lenses and sometimes mirrors to make distant objects appear larger.
What microscope means?
A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is.
What is the meaning of Space Telescope?
space telescope in American English a satellite put in orbit around the earth and equipped with an extremely accurate reflecting telescope, cameras, etc.: it is designed to relay astronomical data to the earth.
How do you describe a telescope?
A telescope is an instrument designed for the observation of remote objects. Telescopes work by employing one or more curved optical elements – lenses or mirrors – to gather light or other electromagnetic radiation and bring that light or radiation to a focus, where the image can be observed, photographed or studied.
