I don't understand how to calculate the n values from the wavelength.

Answer 1

This is how the calculation,as asked in the question, for line 1 is done. For other line 2 and 3, keeping all other factors constant and changing the value of wavelength as mentioned in table, values of n₂ (initial energy level) can be calculated
