Assuming that the incident radiation is capable of ejecting photo electrons from all the given metals, the lowest kinetic energy of the ejected photoelectron is observed with which of the given metals?

If two particles $A$ and $B$ are moving with the same velocity, but wavelength of $A$ is found to be double than that of $B.$ Which of the following statements are correct?

On the basis of Bohr's model, the radius of the $3^{\text{rd }}$ orbit is

A subshell $\mathrm{n}=3, \mathrm{l}=2$ can accommodate maximum of

If the energies of two light radiations $E_1$ and $E_2$ are $25\mathrm{eV}$ and $100\mathrm{eV}$ respectively, then their respective wavelengths ${\lambda }_1$ and ${\lambda }_2$ would be in the ratio ${\lambda }_1:{\lambda }_2=$

If the work function for the photoelectron emission of a metal is $3.75\mathrm{eV}$, then the threshold wave length of the radiation needed for the ejection of the electron is approximately

With increasing Principal Quantum number, the energy difference between adjacent energy levels in H-atom
