What is the smallest value of n for which the wavelength of a Balmer series line is less than 400 nm?

Solution 6P

Step 1 of 2</p>

Here, we have to calculate the smallest value of for Balmer series for which the wavelength is less than 400 nm.

The equation for the wave number,

Where, - Rydberg constant

- ‘n’ value corresponding to the series

- the ‘n’ value corresponding to the state
