What does 'half-silvered' mean in the context of one-way mirrors?

• The silver is only applied to the edges of the mirror.

• The silver layer is thin, creating a blend of transparent and reflective surfaces

• Half of the mirror's surface is covered with silver, and half is left as plain glass.

• The silver is mixed with another metal to reduce its reflectivity.

Why can't light transmit through a regular mirror?

• Because light is absorbed by the glass.

• Because the mirror is always placed in dark areas.

• Because the silver layer and paint make the mirror opaque.

• Because the glass is too thick for light to pass through.
