1. Low Consumption; Wide Application; Small Size; Stable Performance; Exquisite Workmanship. 4. In Fact, for Waves Are An Inherent Attribute Of Geophysical Characteristics. They Form An Electromagnetic Resonance Cavity On The And Ionosphere, And 7.83HZ Is The Natural Frequency Of This Resonance Cavity. 2. Wave Generator, We Call It for Wave Generator, But We Usually Call It Metaphysical Wave Generator. 3. It Is Essentially An Extremely Low Frequency () Electromagnetic Wave. According To The Wavelength Multiplied By The Frequency Of The Speed Of Light, The Wavelength Of The 7.83hz Electromagnetic Wave Is 38,000 Kilometers, Which Is Very Close To The Well-Known Circumference Of The Earth Of 40,000 Kilometers. 5. When Electromagnetic Waves Of Such A Frequency Are Emitted, A Standing Wave Be Formed In The Earth's Space, Which Oscillate Continuously For A Long Time., Weight: 0.49383546688 pounds, Manufacturer: pofaa
