Question

Total spectral lines in balmer series n=2 from n2=5 will be

Answer 1

$\Huge\underline{\underline{\sf Answer}}$

$\large\underline{\underline{\sf Total\:no.\:of\: spectral\:line\:is\:6}}$

$\Huge\underline{\underline{\sf Solution}}$

$\large\underline{\underline{\sf Given:}}$

• $\sf{n_1=2}$

• $\sf{n_2=5}$

$\large\underline{\underline{\sf To\:Find:}}$

• Total spectral line in balmer series of $\sf{n_1\: and\:n_2}$ (N)=?

_________________________________________

We know that :

$\large{\boxed{\sf N=\frac{(n_2-n_1)(n_2-n_1+1)}{2}}}$

$\large\implies{\sf N=\frac{(5-2)(5-2+1)}{2} }$

$\large\implies{\sf N=\frac{3×4}{2} }$

$\large\implies{\sf N=\frac{12}{2}}$

$\large{\sf N=6 }$

Hence

$\large\underline{\underline{\sf Total\:no.\:of\: spectral\:line\:is\:6}}$
