Answer 1

Answer:

Most objects, however send back some light, which falls on their surface. Silver metal is one of the best reflectors of light. A polished block of silver metal reflects almost all the light falling on it and does not transmit or absorb any of the light rays. The smooth and polished surface of the silver metal can get easily scratched and may turn rough. In order to avoid this, ordinary mirrors are made by coating a thin layer of silver metal or mercury on one side of a plane glass sheet and this silver layer is protected by applying a coat of red paint over it.

Explanation:

Hence, the black silvered surface of a plane mirror reflects most of the light incidents on it.
