The wavelength of the first line of Lyman series for \(\mathrm{H}\) - atom is equal to that of the second line of Balmer series for a \(\mathrm{H}\)-like ion. The atomic number \(\mathrm{Z}\) of \(\mathrm{H}\)-like ion is
- A 4
- B 1
- C 2
- D 3
Answer & Solution
Correct Answer
(C) 2
Step-by-step Solution
Detailed explanation
Lyman series of \(\mathrm{H}\)-atom, we can write \(\frac{h c}{\lambda}=R h c\left(\frac{1}{1^2}-\frac{1}{2^2}\right)\) where, symbols have their usual meaning and for second line of Balmer series of \(\mathrm{H}\)-like ion…
