This scale that compares the length of different electromagnetic radiation waves to marine creatures and objects might be helpful to people studying or teaching basic physics.
A high-energy gamma ray’s wavelength is shorter than an atom’s width. A high-frequency, lower energy radio wavelength, meanwhile, can fit three blue whales lined up from snout to fluke. At the longest end of the spectrum sit extremely low frequency radio waves, which can have a wavelength more than 6,000 miles long and are naturally produced by lightning and stars. These can penetrate ocean water and have been used to communicate with submarines.
After years of delays, Russia is preparing to launch a Soyuz 2-1a rocket from the new Vostochny cosmodrone near the Chinese border.
Vostochny was built to eventually ease reliance off the historic Baikonur cosmodrome, which is located on Kazakhstan land leased to Russia.
The inaugural Soyuz has been undergoing prolonged prelaunch checkouts in the new spaceport’s facilities, making sure both they and the vehicle are properly working. Rollout occurred March 21, and the vehicle returned to its integration hall a week later.
Launch is tentatively scheduled for April 25 and will loft a satellite aiming to study high-energy cosmic rays, gamma rays and the magnetosphere.
