145545 A hydrogen atom goes to excited state absorbing a photon with wavelength $\frac{100}{99 R} \stackrel{\circ}{A}$ where $R$ is the Rydberg constant. If this absorption corresponds to a transition line in the Lyman series, calculate the energy of the excited state.

145547 In the hydrogen atom the ratio of wavelengths of the Balmer transition $(n=4$ to $n=2)$ to Lyman transition $(n=3 \rightarrow n=1)$ is

145548 A light beam travelling in the $\mathrm{X}$-direction is described by the electric field $E_{y}=(600 \mathrm{~V} / \mathrm{m})$ $\sin (\omega t+\phi)$. An electron is constrained to move along the Y-direction with a speed of $1.0 \times$ $10^{7} \mathrm{~m} / \mathrm{s}$. Find the maximum magnetic force on the electron.

145549 The electron in hydrogen atom is initially in the third state. When it finally moves to ground state, the maximum number of spectral lines emitted are
