Which energy level transition among the following will have the least wavelength?

Step-by-step solution

According to energy, E= h m v or E= h c i.e E 1 Here, energy of electrons is inversely proportional to wavelength i.e. greater the difference between the transition, lesser will be the wavelength. aligned & n n₄-n₃=n₁ & n₄ n₂=n₂ & n₄ n₁=n₃ i.e. highest energy level transition & n₂ n₁=n₁ & n₄ n₁ having higher energy level transition. aligned n₄ n₁ having higher energy level transition. So, it has least wavelength So, it has least wavelength 1 =R_ H [ 1 n₁^2 - 1 n₂^2 ] R_ H = Rydberg constant, aligned & 1 =R_ H [ 1 1
