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.
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.
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.
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 concave or positively accelerated curve?
Semi spherical/cresent,i.e. An egg.
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 the similarities and differences between concave and convex mirrors?
Definitions found on www.dictionary.com Concave: a curved like a segment of the interior of a circle or hollow sphere; hollow and curved Convex:having a surface that is curved or rounded outwardsBoth concave and convex mirrors are spherical mirrorsconcave mirrora spherical mirror whose reflecting surface is curved inwards is called a concave mirrorconvex mirrora spherical mirror whose reflecting surface is curved outwards is called a convex mirror
What are curved mirrors?
Curved mirrors are mirrors that have a spherical side. example - concave and convex.
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 spherical mirror has a virtual focus-concave or convex?
A concave mirror has a virtual focus. This is because the rays of light that are incident on a concave mirror are reflected and appear to diverge from a point behind the mirror, creating a virtual focus.
