Transparency (projection)

Transparency is when you can see through something, like when you look through a window. In projection, transparency means that you can project an image onto a see-through surface like a projector screen or a piece of clear plastic. That way you can see both the image and what's behind it. Think of it like a magic picture that you can see through! This is useful in presentations or lectures when you want to show something on the screen while also showing what's behind it.
