How the wife signal spreads

Method one: To wear a wall like Harry Potter

Both the wife signal and the broadcast signal are essentially electromagnetic waves. X-ray penetration is strong so it can penetrate the body to take photos, but the wife signal as electromagnetic waves can penetrate the wall, but his penetrating ability is too weak. The higher the electromagnetic frequency, the stronger his penetrating power, the wife signal we used was only 2.4 Hz. The visible frequency of the same electromagnetic wave is a hundred thousand of times times that of the wife, not to mention the X-ray. So wife signal through the wall, will be the wall of steel and cement absorbed a lot.

Method Two: Detour

Wife as a wave, interference and diffraction phenomena occur when encountering obstacles. That's detour. Although Detour is far away, it is relatively easy and convenient. The wife signal received from home is from this road. This way the longer the wavelength of the electromagnetic wave, the more he will be able to bypass. However, although the wife signal is also electromagnetic wave, but belongs to the category of microwave. The wavelength is much shorter than the broadcast. So its ability to bypass obstacles is not so strong, more important is the structure of the family complex, wife signal through the wall is easy to be absorbed, the detour is easy to get in the way.
