Hydrogen atoms are excited by a laser to the ????=4 state and then allowed to emit. What is the maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system?

Respuesta :

Answer:

so total 6 spectral lines are possible here

Explanation:

Since the electron is at excited state of n= 4

so here we have electron from nth excited to lower possible state

here the lower most energy state is ground state

so we will have

[tex]N = ^nC_2[/tex]

here we know

n = 4

[tex]N = ^4C_2[/tex]

[tex]N = \frac{4(4 -1)}{2}[/tex]

[tex]N = 6 lines[/tex]

so total 6 spectral lines are possible here
