Eli5: How does wireless transmission penetrate through walls?
In: Physics
How deep into a forest could you throw a ball?
It probably depends on how dense the forest is and what size the ball is right?
You’re thinking of walls as solid. But they’re really just a dense forest of particles. Think of it like a forest with only inches between each tree. Your hand doesn’t pass through the wall because it’s like a big giant beach ball — it will definitely hit a tree. But something smaller like a tennis ball, might pass through.
A photon is small and moves fast. It’s like a bullet. There’s a good chance it gets through.
