I objected to this statement at first, as frequency plays a big part in what electromagnetic radiation does, but then I discovered many microwave ovens do operate at 2.45GHz
Though, before you freak out that you are cooking your family, consider that a microwave oven outputs 600-1200 watts, while a WiFi antenna is typically 0.5-1 watt.
The "resonating" explanation is wrong. Please stop propagating this mistake.
From Wikipedia: "Sometimes, microwave heating is explained as a resonance of water molecules, but this is incorrect; such resonances occur only at above 1 terahertz (THz)."
