How does the reflectivity of a mirror affect its ability to produce clear and sharp images?

The reflectivity of a mirror affects its ability to produce clear and sharp images by determining how much light is reflected back to the viewer. A mirror with high reflectivity will produce a clearer and sharper image because it reflects more light, resulting in a brighter and more detailed reflection. Conversely, a mirror with low reflectivity will produce a dimmer and less detailed image.
