wokeh, kali ini lagi pengen nulis catetan tentang glombang freq, dan di bawah ini adalah beberapa range freq dan juga fungsi2 kegunaannya.

• < 3 Hz, [100,000 km] = Natural and man-made electromagnetic noise

• Extremely low frequency = 3–30 Hz [100,000 km – 10,000 km] = Communication with submarines

• Super low frequency = 30–300 Hz [10,000 km – 1000 km] = Communication with submarines

• Ultra low frequency = 300–3000 Hz [1000 km – 100 km] = Submarine communication, Communication within mines

• Very low frequency = 3–30 kHz [100 km – 10 km] = Navigation, time signals, submarine communication, wireless heart rate monitors, geophysics

• Low frequency = 30–300 kHz [10 km – 1 km] = Navigation, time signals, AM longwave broadcasting (Europe and parts of Asia), RFID, amateur radio

• Medium frequency = 300–3000 kHz [1 km – 100 m] = AM (medium-wave) broadcasts, amateur radio, avalanche beacons

• High frequency = 3–30 MHz [100 m – 10 m] = Shortwave broadcasts, citizens' band radio, amateur radio and over-the-horizon aviation communications, RFID, Over-the-horizon radar, Automatic link establishment (ALE) / Near Vertical Incidence Skywave (NVIS) radio communications, Marine and mobile radio telephony

• Very high frequency = 30–300 MHz [10 m – 1 m] = FM, television broadcasts and line-of-sight ground-to-aircraft and aircraft-to-aircraft communications. Land Mobile and Maritime Mobile communications, amateur radio, weather radio

• Ultra high frequency = 300–3000 MHz [1 m – 100 mm] = Television broadcasts, microwave ovens, microwave devices/communications, radio astronomy, mobile phones, wireless LAN, Bluetooth, ZigBee, GPS and two-way radios such as Land Mobile, FRS and GMRS radios, amateur radio

• Super high frequency = 3–30 GHz [100 mm – 10 mm] = radio astronomy, microwave devices/communications, wireless LAN, most modern radars, communications satellites, satellite television broadcasting, DBS, amateur radio

• Extremely high frequency = 30–300 GHz [10 mm – 1 mm] = radio astronomy, high-frequency microwave radio relay, microwave remote sensing, amateur radio, directed-energy weapon, millimeter wave scanner

• Terahertz or Tremendously high frequency = 300–3,000 GHz [1 mm – 100 μm] = Terahertz imaging – a potential replacement for X-rays in some medical applications, ultrafast molecular dynamics, condensed-matter physics, terahertz time-domain spectroscopy, terahertz computing/communications, sub-mm remote sensing, amateur radio

dan contoh beberapa glombang yang di pake di endonesiyah.

nah karena blm dapet wangsit, yah baru dapet sedikit ide dari mamas yang ini
jadi guwa cari wangsit lagi klo gtu.
