What is the wavelength corresponding to the frequency of this emission?
The Russian Space Agency plans to place a radio telescope into an even higher orbit than the Japanese HALCA telescope. Using this telescope in concert with the VLBA, baselines as long as 77,000 km may be obtainable. Astronomers want to use this combination to study radio emission from distant objects called quasars at a frequency of 1665 MHz
wavelength = frequency / speed (of light in this case)
= 1665 x 10^6 Hz / 343 m/s
= 4.8542 x 10^6 m = 4854.2 km
wavelength = frequency / speed (of light in this case)
= 1665 x 10^6 Hz / 343 m/s
= 4.8542 x 10^6 m = 4854.2 km
