A two-way mirror, also known as a one-way mirror, is a mirror that is coated with a thin layer of metal or reflective material. This coating allows people on one side of the mirror to see through to the other side, but people on the other side of the mirror can only see their own reflection. Two-way mirrors are often used in interrogation rooms, security settings, and other situations where it is important to observe people without being seen.
There are a few different ways to detect a two-way mirror. One way is to look for a slight distortion in the reflection. If the reflection is not perfectly clear, it may be a sign that you are looking at a two-way mirror. Another way to detect a two-way mirror is to hold your hand up to the mirror. If you can see your fingers through the mirror, it is likely a two-way mirror.
