Shadowgraph
Okay, let me explain shadowgraph in a simple way. You know when you stand in front of a light, you see your shadow on the ground or wall? That's what shadowgraph is!
But, instead of just your body, we use it to see things that are very small and hard to see with our eyes. We shine a light on the thing we want to see, and then we look at the shadow the light makes.
It's like when you hold up your hand to a flashlight, and you see the shape of your hand on the wall. But instead of your hand, we can see things like tiny particles or even the shape of a fluid which can be really helpful for scientists and engineers to understand how things move and change.
Sometimes, we use special cameras and computer programs to help us see and analyze the shadowgraphs, but the basic idea is just shining a light and looking at the shadow it makes.
