Tarzan · Answer 1

The wavelength for the electron transition that results in the greatest release of energy is 400.

Explanation:

Following the equation for energy (E) and wavelength (λ) E = hc/λ

where:

h = planck's constant

c = speed of light

knowing that we have 11 lines in thevisible region from these 11 lines we choose the line located in the shortest wavelength due to as we see in the equation a great energy value requires a short wavelength.

The visible region goes from 400 to 800 nm so the shortest wavelength will be 400 nm
