This article mainly introduces the difference between light transmission and transparency. Let's take a look at it together.
When light passes through a homogeneous medium, the light will propagate in the same direction, and at this time it feels transparent, such as: glass, PC endurance board, etc. When the light passes through the inhomogeneous medium, it will propagate in different directions. This is what we call scattering. At this time, it feels opaque, such as: frosted glass, FRP lighting board, etc.
So we say that the light transmittance of an object that looks transparent is not necessarily better!
