Question

The highest energy in Balmer series, in the emission spectra of hydrogen is represented by $(R_H=109737c{m}^{-1})$

• A. 4389.48 cm^-1
• B. 2194.74cm^-1
• C. 5486.85cm^-1
• D. 27434.25cm^-1

Answer 1

The correct option is D 27434.25cm^-1

$\overline{\theta }=\frac{1}{\lambda }=R_H(\frac{1}{n_1^2}-\frac{1}{n_2^2})$
$=109737\times 1^2(\frac{1}{2^2}-\frac{1}{{\infty }^2})=27434.25$
