Question

from which surfaces of a mirror the polished surface or silvered surface does most of the light reflect

Answer 1

The most of the light is reflected by the silvered surface of the mirror.

• There are two basic layers of a traditional mirror.

1) polished glass surface. (External)

2) silvered surface. (Internal)

• The light rays are mostly reflected by the internal layer of the mirror.

• Now,more than 95% of the light rays are reflected by the silvered surface of the mirror and less than 5% of the light rays is reflected by the polished glass surface of the mirror.

Answer 2

Answer:

•The polished surface of mirror forms the front surface of the mirror and the back surface of mirror is silvered.

•When light ray falls on the front surface, it enters the glass plate and falls on silvered surface. It gets reflected from the silvered surface and goes out from the front surface.

•In general, we neglect the thickness of glass plate of mirror and consider the mirror as a single surface.

Thus, silvered surface does most of the light reflection.
