The wavelength of the first spectral line of the Lyman series of hydrogen spectrum is

In a hydrogen atom, an electron of mass $9.1\times {10}^{-31} \mathrm{kg}$ revolves about a proton in circular orbit of radius $0.53 \mathrm{A}.$ The radial acceleration and angular velocity of electron are respectively

When a hydrogen atom emits a photon during a transition from $n=4$ to $n=2,$ its recoil speed is about

Potential energy between a proton and an electron is given by $U=\frac{K{e}^2}{3R^3}$, then radius of Bohr's orbit can be given by

The ionization potential of hydrogen atom is $13.6 \mathrm{V}$. How much energy need to be supplied to ionize the hydrogen atom in the first excited state.

The angular momentum of the orbital electron is integral multiple of:

The shortest wavelength of $X$-rays emitted from an $X$-ray tube depends upon

In a diffraction pattern due to a single slit of width $\text{'}a\text{'}$, the first minimum is observed at an angle $30°$ when light of wavelength $500 \mathrm{nm}$ is incident on the slit. The first secondary maximum is observed at an angle of
