Concave lenses are thicker at the edges then at the middle. A Convex lens is a lens that is thicker in the center than at its edges.
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.
The telescope is cylindrical. Its primary mirror is concave.
Yes they do. They also include concave mirrors and a plane mirror.
concave & convex
A mirror that bows inward is called concave. The opposite, a mirror that bows outward would be called convex. Convex mirrors are used to to increase the field of view around corners and blind spots. Concave mirror serve no purpose other than novelty (making you appear thin or odd)
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
Concave shapes curve inward, like a cave, while convex shapes curve outward, like a bump.
Convex shapes curve outward, like a dome, while concave shapes curve inward, like a cave.
A non convex is a concave and a convex is differently shaped
A concave polygon has lines that curve inwards whereas a convex polygon has lines that curve outwards and they are found on and inside spheres
Concave curves in (like a cave) = ) and convex curves out = (
Concave shapes curve inward, like a cave, while convex shapes curve outward. To distinguish between them, you can look at the direction in which the shape curves - concave curves inwards, while convex curves outwards.
Concave surfaces are inwardly curved, causing light to be focused towards a single point (e.g., a concave mirror), resulting in a real image. Convex surfaces are outwardly curved, causing light to be spread out or dispersed, resulting in a virtual image. In the dark, a concave surface may appear darker as it focuses light away, while a convex surface may appear lighter as it scatters light.
A concave lens is a lens in which the ends are thicker than the middle, rather shaped like this ---> )( A convex lens is a lens in which the ends are thinner than the middle, shaped like the following ---> ()
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
It can be convex or concave.
The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.
