A hydrogen atom is ground state absorbs \(10.2 \mathrm{~eV}\) of energy. The orbital angular momentum of the electron is increased by
Angular momentum of an electron in hydrogen atom is \(\frac{3 h}{2 \pi}\) (\(h\) is the Planck's constant). The KE of the electron is
A proton moving with a momentum \(p_1\) has a kinetic energy \(1 / 8\)th of its rest mass-energy. Another light photon having energy equal to the kinetic energy of the possesses a momentum \(p_2\). Then, the ratio \(\frac{p_1-p_2}{p_1}\) is equal to
The radius of hydrogen atom in the ground state is 0.53\(\mathop A\limits^o\). After collision with an electron, it is found to have a radius of 2.12\(\mathop A\limits^o\), the principal quantum number \(n\) of the final state of the atom is
