The Lockheed SR-71 Blackbird is the current record-holder for a crewed airbreathing jet aircraft. An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), [1] which also ratifies any claims. Speed records ...
Radio waves in this band have wavelengths from ten to one millimeter, so it is also called the millimeter band and radiation in this band is called millimeter waves, sometimes abbreviated MMW or mmWave. [3] Some define mmWaves as starting at 24 GHz, thus covering the entire FR2 band (24.25 to 71 GHz), among others. [4] [5]
The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. Radio waves, at the low-frequency end of the spectrum, have the lowest photon energy and the longest wavelengths—thousands of kilometers, or more.
Highest speed recorded during a free fall set by Felix Baumgartner. 428: ... Typical speed of a Moreton wave across the surface of the Sun. 1,610,000: 5,800,000:
Acoustic – G 10, the highest pitch sung by Georgia Brown, who has a vocal range of 8 octaves. 44.1 kHz: Common audio sampling frequency: 10 5: 100 kHz: 740 kHz: The clock speed of the world's first commercial microprocessor, the Intel 4004 (1971) 10 6: 1 megahertz (MHz) 530 kHz to 1.710 MHz: Electromagnetic – AM radio broadcasts 1 MHz to 8 MHz
The World Meteorological Organization, or WMO, has announced in a recent news release that it now belongs to a 62.3-foot-high-wave. 62-foot-high wave becomes highest ever recorded Skip to main content
HF's position in the electromagnetic spectrum.. High frequency (HF) is the ITU designation [1] [2] for the band of radio waves with frequency between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).
While it may have been designed as the fastest propeller-driven aircraft, this goal was never realized due to severe stability problems. [7] This record speed is also inconsistent with data from the National Museum of the United States Air Force, which gives a top speed of "only" 840 km/h (520 mph; 450 kn) or Mach 0.70.
