If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. since the electron is de-exited from 1(st) exited state (i.e n = 2) to ground state (i.e n = 1) for first line of Lyman series. In physics, the Lyman-alpha line, sometimes written as Ly-α line, is a spectral line of hydrogen, or more generally of one-electron ions, in the Lyman series, emitted when the electron falls from the n = 2 orbital to the n = 1 orbital, where n is the principal quantum number.
