Question

why our image is not clear when we see our face in old plate​

Answer 1

Whenever we try to look at ourselves on an old metallic plate, the reflection formed is unclear. This is because, due to constant usage (for serving, eating, or even washing purposes), the metallic plate develops fine irregularities over its surface. Thus, with the formation of unevenness by scratches and rubbing, the reflection created by a used metallic plate is not clear.
