Why is the focal points of a convex lens is real and concave is virtual?
The convex mirror diverges light rays, so if you draw the reflected rays in front of the mirror and continue drawing them at the back of the mirror the virtual light rays (at the back of the mirror) will join. This point is called a Virtual Focus Point.
What is the difference between concave mirror and convex mirror?
Eyesight = ------< = the lines are pointing to how it sees. You see things more clearly for far away things> = the lines are pointing to how it sees. You see things more clearly for close objects.Concave: ---------)(> objectConvex: ---------)< objectI hope you understand the answer. I didnt explain it too well.or you could try......concave is like a "cave"..it bends inwardsand convex is just the opposite it bends outwards....//nfjn//....concave mirror is the one which forms the inner part of the spherical mirror or its reflecting surface bulges inwards & convex is the one which bulges outwards. concave always forms real & inverted image while convex forms virtual & erect image
What kind of mirror is used for flashlight?
Concave Mirrors, so that the light can be concentrated and so that it points forward. This is how we are able to see using a flashlight beam.:) Catherine
Why do convex mirrors always form the same image?
They do not always create the same image. They have different focal points and objects at different distances which create an image different from the object in magnitude or orientation.
What is an antinode?
in a wave there are some points which vibrate with maximum amplitude these points are called antinodes.pressure at\on these points is minimum hence they are also called pressure nodes.
Is a yield sign concave or convex?
It is convex because you can draw a straight line between any two points on it without having to take your pen off of the sign.
Why is this statement false a polygon is concave if no diagonal contains points outside the polygon?
It should be convex
What is the difference between a convex shape and a concave shape?
i dont think any1 knows * * * * * A concave polygon has at least one reflex angle. Equivalently, in a convex polygon, a line joining ANY two points in (or on) the polygon lie wholly within (or on) the polygon. In a concave polygon there are at least two points for which the line joining them does not lie wholly inside (or on) the polygon.
What the difference between convex and non convex polygons?
In a non-convex (or concave) polygon, at least one interior angle is a reflex angle. An alternative definition is that if you take any two points inside a conves polygon, the line joining them is wholly inside the polygon.
Concaved is what?
If a shape is said to be concave, it means that it is possible to have two points that to connect, need a straight line segment that must cross outside of the shape. An example would be a cross. Others include the following symbols: +, v, L, x, z, and many others. The opposite of concave is convex.
Why is the focal points of a convex lens is real and concave is virtual?
The convex mirror diverges light rays, so if you draw the reflected rays in front of the mirror and continue drawing them at the back of the mirror the virtual light rays (at the back of the mirror) will join. This point is called a Virtual Focus Point.
What is a convex figure?
In a convex figure, if you pick any two points, the points between them are also a part of the figure.
What is differentiale convex and non-convex?
Take any two points on or inside a body. If every point on the straight line joining the two points lies within the shape, then it is convex. If not, it is non-convex.
Can a triangle be concave?
No, you would need at least 4 points to create a concave polygon.
What does convex mean in geometric terms?
Having all internal angles below 180 degrees * * * * * That only applies to polygons or polyhedra. You can have convex solids that are curved and have no angles. A convex shape is one in which, if you take any two points on the surface of the shape or inside it, then the whole of the straight line joining those two points is on the surface of the shape of inside it.

In at most How many points do the diagonals of a convex hexagon intersect?
15 points.
