why is mirror silvered at black?​

Answer 1

Answer:

Whether new or old, many mirrors desilver at some point during their lifetime. Dark edges around the outside of a mirror is a telltale sign that the silver backing is lifting and being worn away. The dark spots will eventually work their way in further. Moisture is usually the primary culprit and cause of desilvering

Answer:

Answer:One surface of the mirror is silver because it helps the light rays to reflect. If it is not polished the rays pass through the mirror. So silver helps the rays to reflect properly
