145772 Frequency of the series limit of Balmer series of hydrogen atom in terms of Rydberg constant $R$ and speed of light $c$ is

145773 Calculate the highest frequency of the emitted photon in the Paschen series of spectral lines of the Hydrogen atom.

145775 Electrons ejected from the surface of a metal, when light of certain frequency is incident on it, are stopped fully by a retarding potential of $3 \mathrm{~V}$. Photoelectric effect in this metallic surface begins at a frequency $6 \times 10^{14} \mathrm{~s}^{-1}$. The frequency of the incident light in $\mathrm{s}^{-1}$ is [Planck's constant $=6.4 \times 10^{-34} \mathrm{Js}$, charge on the electron $=1.6$ $\left.\times 10^{-19} \mathrm{C}\right]$

145776 $\Delta \lambda$ is the difference between the wavelengths of $K_{\alpha}$ line and the minimum wavelength of the continuous $X$-ray spectrum when the $X$-ray tube is operated at a voltage $V$. If the operating voltage is changed to $V / 3$, the above difference is $\Delta \lambda^{\prime}$. Then
