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.
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.
Concave mirrors can distort the reflection of the face, making it difficult to accurately apply makeup. The curved surface can also cause the image to appear magnified or shrunk in certain areas, leading to uneven application. Additionally, concave mirrors can create sharp, focused reflections that may not provide a true representation of how the makeup looks in natural lighting.
Mirrors need to have smooth surfaces to reflect light efficiently and accurately. Any imperfections or roughness on the surface can cause light to scatter or be distorted, resulting in a blurry or distorted reflection. Smooth surfaces help produce clear and sharp images.
When light falls on a mirror, it is reflected back towards the source. This reflection occurs based on the law of reflection, where the angle of incidence is equal to the angle of reflection. Mirrors are designed to reflect light, allowing us to see clear and sharp images of objects.
The mirror reflectivity affects the quality of the reflected image by determining how much light is reflected back. Higher reflectivity mirrors produce clearer and brighter images, while lower reflectivity mirrors may result in dimmer and less sharp images.
Cameras use mirrors in their optical systems to reflect and redirect light onto the image sensor, which captures the image. Mirrors help to focus the light and create a clear and sharp image.

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.
Adaptive optics technology can enable ground-based telescopes to achieve images as sharp as those from the Hubble Space Telescope. This technology involves using mirrors that can change shape to compensate for the distortions caused by Earth's atmosphere, allowing for clearer and more detailed images.
A projector typically uses a concave lens to focus and project light onto a screen. The concave shape helps to converge the light rays and create a sharp image.
A silvered mirror is coated on the back with a layer of silver to create a reflective surface. This reflective backing enhances the mirror's ability to reflect light and create clear, sharp images.
A smoother mirror surface will reflect light more uniformly, resulting in a clearer image. Rough mirrors may scatter light in different directions, causing distortion and reducing the clarity of the reflected image. This is why high-quality mirrors with smooth surfaces are used in optics to achieve sharp and accurate image reflections.
The recommended resolution for printing high-quality images at 300 dpi ensures they are clear and sharp.
