A stationary hydrogen atom emits a photon corresponding to the first line of the Lyman series. What is the velocity of recoil of the atom? `(m_(H)=1.6

Correct Answer - `20 eV, 13.2 eV`

Correct Answer - `5.4 xx 10^(-7) %`

Correct Answer - [10 us by both]

Correct Answer - 1215.14 Å

Correct Answer - 5893 Å

Correct Answer - `[3.4 xx 10^(5) m//s, 0.020]`

Correct Answer - `[11.2eV]`

Correct Answer - `[1224 Å]`

Correct option is: (D) 500 m/s Using conservation of linear momentum. \(m_1 \ v_1 = m_2 \ v_2\) \(v_1 = \frac{m_2 \ \times \ v_2}{m_1}\) \(v_1 = \frac{1 \times 5}{10 \times 10^{-3}}\) \(v_1 = \frac{5000}{10}\) \(v_1 =...
