Краткое описание:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The hydrogen line, 21 centimeter line or HI line refers to the electromagnetic radiation spectral line that is created by a change in the energy state of neutral hydrogen atoms. This electromagnetic radiation is at the precise frequency of 1420.40575177 MHz, which is equivalent to the vacuum wavelength of 21.10611405413 cm in free space. This wavelength or frequency falls within the microwave radio region of the electromagnetic spectrum, and it is observed frequently in radio astronomy, since those radio waves can penetrate the large clouds of interstellar cosmic dust that are opaque to visible light. Note that the relationship between the frequency and the wavelength is found from the simple equation that says that the wavelength equals c divided by the frequency measured in hertz.
