The Balmer series is particularly useful in astronomy because the Balmer lines appear in numerous stellar objects due to the abundance of hydrogen in the universe, and therefore are commonly seen and relatively strong compared to lines from other elements.
Deret Balmer ini sangat berguna dalam astronomi karena garis Balmer muncul di berbagai objek bintang karena banyaknya hidrogen di alam semesta, dan oleh karena itu sering terlihat dan relatif kuat dibandingkan dengan garis dari unsur-unsur lain.
