Question:

Arrange the following lines of Balmer series in the increasing order of their wavelength

A. $H_{\delta}$

B. $H_{\beta}$

C. $H_∞$

D. $H_{\gamma}$

E. $H_{\alpha}$

Choose the correct answer from the options given below :

Options:

C, A, D, B, E

E, B, D, A, C

E, B, D, C, A

C, A, B, D, E

Correct Answer:

C, A, D, B, E

Explanation:

The correct answer is option (1) : C, A, D, B, E

$E∝\frac{1}{\lambda}$

$⇒\lambda ∝\frac{1}{E}$

$⇒$ For maximum energy wavelength would be ,axi,u,/

$⇒ H_{\alpha }> H_{\beta} > H_y > H_{\delta} > H_∞$

$⇒C, A, D, B, E$
