How can microwaves be blocked?

Microwave energy radiates at wavelengths ranging from 1 millimeter to 1 meter, and frequencies ranging from 300 GHz to 300 MHz. High frequency radio frequency energy is radiated at wavelengths from 10 meters to 100 meters, and frequencies from 30 MHz to 3 MHz. read more

The problem is that both microwave ovens and Wi-Fi operate on the same frequency, 2.4 GHz. In theory, a properly shielded microwave shouldn't leak any radiation, but the reality is that they leak quite a bit, resulting in electromagnetic, or radio-frequency (RF), interference. read more
