It depends on the precise shape of the mirror. What's generally meant by "sharp image" is that the light rays focus at a single point. If the curvature of the mirror is variable, this doesn't happen.

Why convex mirrors are fixed on very sharp turns of the roads of the mountains?
Convex mirrors are fixed on very sharp turns of the roads of mountains Because convex mirror diverges the image and due to divergence we can know about the car coming from the other side of the turn as the image reflected is greater.
Which mirror is suitable for the use of shaving and why?
Any type of mirror, whether plano, convex, or concave, is useful for shaving if it breaks clean with a uniform, straight, sharp edge.
Why do ground glasses not produce any images?
Light falling on such surface gets scattered and hence no sharp image becomes possible.

because convex mirror diverges the image and due to divergence we can know abt the car coming from the other side of the turn as the image reflected is greater.
Should a short sighted person use a concave or convex lens?
This is a lens which is designed to help someone who has problems seeing at distance (myope), the light rays going into your eye are not hitting the fovea (the part of the eye located on the retina which allow you to see clearly) in the proper place, these rays are falling in front of the fovea, so by using a concave ( a minus lens) lens, this moves these light rays by diverging them and moving them back to the fovea which allows for clear vision at distance. At least this is how a concave lens is used optically speaking.this is from winter006: concave mirrors are used in stores and gas stations to see a wider area of the store.It's also called , a Diverging Lens .It is thinnest in the centre and spreads light out , so it gives a diminished image .
What is the difference between parabolic and concave mirrors?
In the case of concave mirrors parallel rays, parallel to the principal axis and incident near the pole(axial rays), after reflection will converge to the principal focus.Rays reflected from the marginal portions of the mirror(marginal rays) will converge to points nearer than the focus. Due to this the image formed by a concave mirror of large aperture will be blurred. This defect is called spherical aberration. This defect can be overcome by using parabolic mirrors. In a parabolic mirror all the rays, axial rays as well as the marginal rays, incidenting on it after reflection will converge to the same principal focus. This is due to the geometric property of the parabola, that is parabola allows only one focus.Hence in a parabolic mirror there is no spherical aberration and the image will be sharp and clear.

Do vertices have to be pointed out?
No, vertices do not have to be pointed out. Vertices are the points where the edges of a shape or object meet. They can be sharp or rounded, depending on the shape or object.
What brain imaging method takes advantage of the magnetic properties of different atoms to take sharp three dimensional images?
Which brain imaging method uses magnetic properties of different atoms to take sharp, three-dimensional images of the brain.
Which brand of electronics are best known for having sharp HDTV?
Sony and Sharp televisions are every good televisions for sharp HDTV. I personally own an Insignia brand HDTV television and I have found that it provides very quality sharp images at all times.
Which mirror is suitable for the use of shaving and why?
Any type of mirror, whether plano, convex, or concave, is useful for shaving if it breaks clean with a uniform, straight, sharp edge.
I saw Avatar on normal TV and want to feel it on 3D TV. Which 3D technology can deliver sharp and bright 3D TV images?
According to me, you have to watch the 3D movie on LG 3DTV integrated with new FPR technology that can deliver sharp and bright 3D TV images because it has 240Hz high speed and helps create 240 images per second.
Are the diaphragmatic surfaces concave or convex and why?
This is a deeply concave surface, often referred to as the base of the lung. It rests on the convex dome of the diaphragm. The concavity is deeper in the right lung because of the higher position of the dome. Laterally and posteriorly, the diaphragmatic surface is bound by a thin sharp margin that projects into the costodiaphragmatic recess.
What is a fine liner pen used for?
a fine liner pen is used for writing &drawing especially in drawing sharp images
How does a concave mirror affect light?
A concave mirror will tend to "focus" light to some degree, depending on the curvature of the mirror. A parabolic mirror will bring reflected light to a sharp focus, and telescopes use this type of curve for the shape of their reflective surface. And for exactly the reasons you think they do.

Why do ground glasses not produce any images?
Light falling on such surface gets scattered and hence no sharp image becomes possible.
Which technology can allow a single ground-based telescope to achieve images as sharp as those from the Hubble Space Telescope?
