Spherical mirrors, which can be either concave or convex, have a history that dates back to ancient civilizations. The earliest recorded use dates to around 3000 BCE in Mesopotamia, where polished metal surfaces served as rudimentary mirrors. By the time of the Greeks, particularly in the work of Archimedes, the principles of reflection were studied more scientifically. The development of glass mirrors in the Middle Ages marked a significant advancement, leading to the modern spherical mirrors used in various applications today.

When were deformed mirrors invented?
Parabolic mirrors were described and studied in classical antiquity by the mathematician Diocles in his work On Burning Mirrors. Ptolemy conducted a number of experiments with curved polished iron mirrors, and discussed plane, convex spherical, and concave spherical mirrors in his Optics.
Who discover spherical mirrors?
Spherical mirrors were understood by ancient Greek philosophers, but it was the Arab scientist Alhazen in the 11th century who provided a detailed explanation of their properties through his work on optics. His writings on spherical mirrors laid the foundation for the understanding of reflection and refraction in optics.
What type of mirror would you use to allow a large area to be viewed?
To reflect the image of a large area, a convex mirror would be used. This mirror would normally be in the form of a spherical section, as the security mirrors in a store or mall. A full mirrored sphere could be used, but would not be as efficient.
How do you use spherical in a sentence?
The spherical rock turned out to be a dinosaur egg.
What person invented the mirror?
The romans. Also it was made by accident Mirrors of polished copper were crafted in Mesopotamia from 4000 BC, and in ancient Egypt from around 3000 BC. In China, bronze mirrors were manufactured from around 2000 BC. Metal-coated glass mirrors are said to have been invented in Sidon (modern-day Lebanon) in the first century AD, and glass mirrors backed with gold leaf are mentioned by the Roman author Pliny in his Natural History, written in about 77 AD. The Romans also developed a technique for creating crude mirrors by coating blown glass with molten lead. (research from wikipedia.com) The history of mirrors dates back to ancient times when mankind first saw reflections in a pond or river and considered it magic. Polished stone or metal was used in the first early man-made mirrors. Later glass was used in combination with metals like tin, mercury, and lead to create mirrors.
What are spherical mirrors?
The most curved mirrors are spherical mirrors. The centre of curved surface is called center of curvature. There are two kinds of spherical mirrors. Concave and convex mirror.
What are curved mirrors?
Curved mirrors are mirrors that have a spherical side. example - concave and convex.
Are the laws of reflection for plane mirrors valid for spherical mirrors?

Is convex and concave mirrors also known as spherical mirrors?
Yes convex and concave mirrors are also known as spherical mirrors. If mercury coating is made on the convex side of the spherical then mirror is known as concave mirror. If mercury coating is made on the concave side the convex portion would reflect the light fallen so it is named as convex mirror. Actual just a small part of the sphere is taken out and this would act as the spherical mirror.
When were deformed mirrors invented?
Parabolic mirrors were described and studied in classical antiquity by the mathematician Diocles in his work On Burning Mirrors. Ptolemy conducted a number of experiments with curved polished iron mirrors, and discussed plane, convex spherical, and concave spherical mirrors in his Optics.

Spherical mirrors were understood by ancient Greek philosophers, but it was the Arab scientist Alhazen in the 11th century who provided a detailed explanation of their properties through his work on optics. His writings on spherical mirrors laid the foundation for the understanding of reflection and refraction in optics.
What are the uses of spherical mirrors?
Spherical mirrors are used in various applications such as telescopes, cameras, and security mirrors. They can be used to collect or diverge light to form real or virtual images, depending on the type of mirror and its curvature. Spherical mirrors are also used in reflecting telescopes to gather and focus light for observation.
Why concave and convex mirrors are called spherical mirrors?
Concave and convex mirrors are called spherical mirrors because their reflecting surfaces are part of a sphere. This means that if the mirror were extended to form a complete spherical shape, it would have the same radius of curvature for all points on its surface.
What is the defect that all the concave spherical mirrors have?
All concave spherical mirrors have a defect known as spherical aberration, which causes light rays coming from a single point on the object to not converge at a single point after reflection, resulting in a blurred image.
What is defect that all concave spherical mirrors have?
The defect that all concave spherical mirrors have is called spherical aberration. This results in the formation of a blurred image instead of a sharp focus due to light rays focusing at different points on the mirror's surface.
Which mirror show virtual image of object placed in front of it?
Plane Mirror And Other Spherical Mirrors Bulged Outside, Such As Convex Mirrors
Is a spherical mirror and concave mirror the same thing?
No, a spherical mirror is a general term that refers to a mirror with a curved surface, while a concave mirror specifically has a reflective surface that curves inward, like the inside of a sphere. Concave mirrors can be one type of spherical mirror, along with convex mirrors.
