How Does Wi-Fi signals: reflection, absorption, diffraction, scattering Work?

Wi-Fi signals travel through the air like invisible bouncy balls that can bounce, hide, twist, and split into smaller balls when they meet things in their way.

Reflection is like when a ball hits a wall and bounces back. If Wi-Fi hits a big metal object like a fridge, it reflects, meaning it sends the signal back the way it came, just like a ball bouncing off a wall.

Absorption happens when something eats up the signal, like a sponge soaks up water. A thick wall or a soft cushion can absorb Wi-Fi signals, making them weaker as they pass through.

Diffraction is like when a ball goes around a corner and keeps moving, it's not blocked completely, just bent a little. If Wi-Fi hits the edge of a door frame, it diffractions, meaning it bends around the corner so you can still get a signal in another room.

Scattering is like when a ball hits a bumpy road and splits into many small balls moving in different directions. When Wi-Fi hits something rough or with lots of little objects, like a curtain, it scatters, sending signals off in many tiny directions, some of which reach your phone!

Examples

  1. A Wi-Fi signal bounces off a wall like a ball hitting a brick.
  2. Your phone struggles to get a signal through a thick concrete wall because the signal gets absorbed.
  3. Wi-Fi signals can bend around corners, allowing your tablet to connect from another room.
