Faisceau

Okay kiddo, imagine you have a bunch of pencils that you need to organize. You can either put all the pencils in a messy pile or you can group them based on their colors or length to make them easier to find.

Now, think of the word "faisceau" as a French word that means "bundle" or "beam" in English. So, when somebody talks about a faisceau, they are referring to a beam of light or a bundle of something.

For example, a faisceau laser is a laser beam that shoots out light in a straight line. It's like shining a flashlight in a dark room and getting a straight line of light.

A faisceau de documents is a bundle of documents that are tied together. It's like when you take all your coloring pages and put them in a folder to keep them safe and organized.

So, a faisceau can be anything that is grouped or bundled together, whether it's light, documents, or even pencils.
