# What is the frequency of limiting line in Balmer series?

##### 1 Answer

#### Answer:

#### Explanation:

The Balmer series corresponds to all electron transitions from a higher energy level to

The wavelength is given by the Rydberg formula

#color(blue)(bar(ul(|color(white)(a/a) 1/λ = R(1/n_1^2 -1/n_2^2)color(white)(a/a)|)))" "#

where

Since

we can re-write the equation as

or

where

In this problem,

as

Thus,
