Specify the formula for calculating the number of the spectral lines in a Hydrogen atom. Identify the number of spectral lines seen for the Hydrogen atom when an electron jumps from to in visible region.
Step 1: Analyze the formula for calculation of spectral line in atom.
The formula for calculating spectral lines:
Number of spectral lines
Where, lower energy level
higher energy level
Step 2: Find number of spectral lines from to
Here it is given that to
By substituting these values in the formula, we get:
Number of spectral line:
Thus, the number of spectral lines seen for Hydrogen atom when electron jumps from to in visible region is
