All visible light (light that our eyes can detect) has a wavelength between 400-700 nanometers.  Wavelengths just smaller than 400 nm are ultraviolet light.  Wavelengths just larger than 700 nanometers are infrared light. What type of light is the Balmer series light that we have considered so far?

The Balmer light series comes under the visible light.

Explanation:

The transition of electrons from higher to energy level with 2 as principal quantum number results in the spectral emission lines of hydrogen atom and this series of lines are known as Balmer series.

Mostly, these lines has the wavelength of more than 400 nm but lesser than 700 nm. Generally of the four categories namely, 410, 434, 486, 656 nm which comes under the type of visible light. So, it can be concluded that the Balmer series light falls under visible light.

In astronomy, Balmer lines occur in various stellar (celestial or astronomical) objects due to the higher content of hydrogen in the universe. Therefore, they are commonly seen and relatively strong when compared to other element lines.

Note: nm is nanometer (one billionth of a meter in length)
