How do Wi-Fi Signals travel through walls and obstacles?

Answer 1

WiFi signal is basically like light. Both light and WiFi signal are in the family of electromagnetic radiation and the same rules apply to them.

So just as light can travel through some objects (like, glass), there are materials and objects that are transparent for WiFi signal.

But just like a very very thick glass that’s hardly transparent anymore for light, a very thick wall is hardly transparent for WiFi signal.

So basically you can imagine a WiFi router as a lamp and the walls made of glass.
