Why do reflecting telescopes use con cave mirrors and not convex mirrors?

Convex mirrors spread and not focus light. They do the opposite of concentrating and magnifying. They are the mirror image of what a concave telescope is and does. Pun intended.

Examples of concave and convex mirrors?
Convex means rounded or curved like the exterior of a circle or sphere. Also called as fish eye or diverging mirror. The mirror coating of the concave mirror is on the outside of the spherical surface. In concave mirrors, the center of curvature and the reflecting surface fall on the same side of the mirror.
Is the lens in a human eye concave or convex?
The lens of the eye is biconvex (convex on both sides).
Write magnification relation in terms of you and v for convex lens and concave mirror?
Convex is () and makes objects appear larger. Concave is )( and makes objects appear smaller. The side rear-view mirrors on cars have concave mirrors, hence, "Object are closer than they appear." Easy way to remember is that a cave is like a hole in the ground, so something is concave if it gets smaller towards the center.
What are the two types of curved mirror called?
they are called concave mirror ... mirrors whose center bulges out are called convex, and can reflect a wider view than a flat mirrored surface, but the objects are "larger than they appear", and also "closer than they appear." These are most often seen on right hand mirrors on vehicles, to help minimise blind spots. mirrors whose center is recessed are called concave (remember the term by thinking of a shallow cave.) Depending upon how close you are to the mirror's focal point, objects appear larger than they really are, or upside down. These are often seen in makeup mirrors so you get a clearer view of your face when shaving or applying makeup. Combinations of both convex and concave mirrors are seen in funhouses of amusement parks, to make the viewer look skinnier and taller, shorter and fatter, or even upside down.
What are the physical attributes of a convex and a concave lens?
convex goes outward and a concave is shaped like a cave.
In which direction does a convex lens bend?
Convex lenses protrude or curve out, concave lenses curve in, like a cave...
What is the difference between concave and convex lens'?
Answer #1convex lens is something they put in your eyes as contacts or in your glasses if you farsited but convex lens makes your image bigger and concave lens makes your image smaller.Answer #2For example, mirrors can be convex, concave and straight, just like glass. The normal mirrors that you use to look at yourself are straight mirrors, they show a normal picture.Do you ever walk into a shop and see a huge bulging mirror in the corner of the shop and you can see just about every corner of the shop in the mirror? well that is a convex mirror. The curved mirrors show a wider view of everything.The concave mirrors are opposite, they "magnify" the image, the concave mirrors make objects larger because the light is focused on a smaller reflection area.This is exactly what happens if you look through glass, that is either a convex or concave.People who are short sighted have glasses with a concavelens, (the lens that indents, you can also remember that it is concave that way because a cave goes in and a concave lens goes in.People who are long sighted wear glasses with convexlenses.
Why do you use concave mirrors on the passenger side?
Actually it is a convex mirror, it bulges out in the center. This increases the field of view from a normal flat mirror so that you can see more area from side to side. So that you can see to the rear and to the side into the blind spot. concave is shaped like the inside of a bowl. Convex is shaped like the outside of a bowl or dome. The hint is to think "cave" inside a cave or bowl so conCAVE
What is concave or convex?
Concave dips inward. (the cave ending clues you in)Convex bumps outward. (it vexes you like a pimple)
Is the cornea convex or concave?
The cornea is convex. Remember that conCAVE curves in the way - like a cave. The cornea is convex as it helps the rays of light to converge (come together). Hope that helps!
Pls give you some examples of concave mirror...?
there are three main types of mirror- 1-flat=normal mirror 2-convex=outward 'bulge' type commonly used in shops for security-gives wide field of view.also on some motor vehicles, usually door mirrors. 3-concave=as the name suggests in facing 'bulge' (as in cave-makes it easy to remember this way)used to concentrate the light to a focal point-used in some telescopes. concave,convex or combinations of both are used in 'fun house' exhibits to radically distort images of the viewer.
Is a camera lens convex?
Yes it is a convex lens just like the one in your eye! A convex lens goes outwards but a concave lens goes inwards (like a cave). Simple! :-) xoxo
