What are uniform shadows?

Uniform shadows are when a shadow looks the same all over, no parts are darker or lighter than others.

Imagine you're playing outside on a sunny day, and you put up a big sheet between you and the sun. That sheet is like a screen that blocks the light. Now, if your friend stands behind that screen, their shadow will be just as dark all over, no parts are brighter or darker than others. That's what we call a uniform shadow.

Think of sunlight as little beams coming from the sun. When something blocks those beams completely, like a big wall or your friend behind that sheet, it’s like putting a blanket over the light. The blanket stops all the beams, so everything on the other side is in complete darkness, and that shadow looks flat and even.

But if you use something with holes, like a sieve or a net, some of the light gets through in little spots. Then your friend’s shadow would have brighter parts, it wouldn’t be uniform anymore. It would look more like a pattern than one solid shade. Uniform shadows are when a shadow looks the same all over, no parts are darker or lighter than others.
