In the Rutherford experiment, $\alpha$-particles are scattered from a nucleus as shown. Out of the four paths, which path is not possible?

A hypothetical atom has only three energy levels. The ground level has energy, $E_1 = - 8$ eV. The two excited states have energies, $E_2 = - 6$ eV and $E_3 = - 2$ eV. Then which of the following wavelengths will not be present in the emission spectrum of this atom?

A diatomic molecule is made of two masses $m_1$ and $m_2$ which are separated by a distance $r$. If we calculate its rotational energy by applying Bohr?'s rule of angular momentum quantization, its energy will be given by : ($n$ is an integer)

The transition from the state $n = 4$ to $n = 3$ in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from
