Can Light Bump Into Other Light?

Light can bump into other light, just like when two kids on a swing set crash into each other.

Imagine you're playing with flashlights in a dark room. Each flashlight is like a kid on a swing, moving through the air. Now, if two flashlights shine at the same spot, something cool happens, their light meets up and creates new patterns, like when two kids bump into each other and start spinning around.

Think of light as a bunch of tiny dancers. Each dancer moves in a line, just like a beam from a flashlight. When two groups of dancers meet at the same place, they can either dance together or step aside, depending on how they move.

This is why sometimes you see bright spots and dark spots when two lights cross, it's like when kids play tag and some are in the middle while others are on the sides. The bright spot is where the dancers joined up, and the dark spot is where they stepped aside. Light can bump into other light, just like when two kids on a swing set crash into each other.
