What type of mirror is used in a spotlight?

A parabolic mirror is typically used in a spotlight. This type of mirror is designed to reflect light rays in a parallel manner, concentrating the light and directing it outward in a beam.

How is spherical aberration eliminated in a reflecting telescope?

A reflecting telescope should have a parabolic mirror in which case there is no spherical aberration. The process of turning a spherical mirror surface into a parabolic one is called 'figuring'.


What is the difference between parabolic and concave mirrors?

In the case of concave mirrors parallel rays, parallel to the principal axis and incident near the pole(axial rays), after reflection will converge to the principal focus.Rays reflected from the marginal portions of the mirror(marginal rays) will converge to points nearer than the focus. Due to this the image formed by a concave mirror of large aperture will be blurred. This defect is called spherical aberration. This defect can be overcome by using parabolic mirrors. In a parabolic mirror all the rays, axial rays as well as the marginal rays, incidenting on it after reflection will converge to the same principal focus. This is due to the geometric property of the parabola, that is parabola allows only one focus.Hence in a parabolic mirror there is no spherical aberration and the image will be sharp and clear.


What kind of telescope uses a single large parabolic mirror to gather and focus starlight?

A single-mirror reflector.


How do you build a parabolic mirror?

A parabolic mirror is shaped such that parallel incident light is reflected to a point called the focus. You will have to establish the size required, and the shape. There is an entry in Wikipedia on Parabola, giving the algebra.


Which mirror is used in search light?

A parabolic mirror is commonly used in searchlights because it can reflect light in a concentrated beam over long distances. Its curved shape helps to focus the light emitted by the searchlight into a powerful and directed beam.


How does a parabolic mirror concave shape affect the reflection of light?

A parabolic mirror with a concave shape focuses incoming light rays to a single point called the focal point. This results in a concentrated and intensified reflection of light, making the mirror useful for applications such as telescopes and satellite dishes.


How does a parabolic mirror prevent spherical aberration?

A parabolic mirror prevents spherical aberration by focusing incoming light rays to a single point, rather than spreading them out. This is achieved because the shape of the mirror is designed to reflect light in a way that corrects for the distortion caused by a spherical shape.


What type of mirror is at the end of a reflecting telescope?

A parabolic mirror, usually. A spherical mirror is also sometimes used, but that requires additional corrections in other parts of the telescope.
