In the hydrogen atom, an electron drops from a higher energy level to a lower energy level emitting a photon of violet light. Which electronic transition is the most likely to emit a photon of violet light The line spectrum for hydrogen shows 4 narrow strips of color on a horizontal black rectangle. The colors of the 4 spectral lines moving from left to right are violet, deep blue, light blue, and red. An arrow beneath the rectangle labeled energy points to the left. 3 ā 2 4 ā 2 6 ā 2 5 ā 2

One of the visible lines in the hydrogen emission spectrum corresponds to the $n=6$ to $n=2$ electronic transition. What color light is this transition?

The radiation emitted by the first excited state of hydrogen as it drops to the ground state is called the Lyman alpha line, and have wavelength 122 nm. An excited hydrogen atom is observed radiating light at wavelength 488 nm. This most likely results from the transition n = 2 ā n = 2. n = 4 ā n = 1. n = 2 ā n = 1. n = 3 ā n = 1. n = 4 ā n = 2.
