Given the value of Rydberg constant is \(10\,\text{m}^{-1}\), the wave number of the last line of the Balmer series in hydrogen spectrum will be
(1). \(0.5 \times 10^7\,\text{m}^{-1}\)
(2). \(0.25 \times 10^7\,\text{m}^{-1}\)
(3). \(2.5 \times 10^7\,\text{m}^{-1}\)
(4). \(0.025 \times 10^4\,\text{m}^{-1}\)
