Einstein's photoelectric equation is
Light of wavelength \(\lambda\) strikes a photoelectric surface and electrons are ejected with kinetic energy \(K\). If \(K\) is to be increased to exactly twice its original value, the wavelength must be changed to \(\lambda^{\prime}\), such that
In which of the following photoelectric effect is not observed?
When \({ }_{92} \mathrm{U}^{235}\) undergoes fission, \(0.1 \%\) of its original mass is changed into energy. How much energy is released if \(5 \mathrm{Kg}\) of \({ }_{92} \mathrm{U}^{235}\) undergoes fission?
The de-Broglie wavelength of a proton \(\left(m=1.67 \times 10^{-27} \mathrm{~kg}\right)\) acclerated through a potential difference of \(2 \mathrm{~kV}\) is
A metal surface is illuminated with photons of energies $E_1=4 \mathrm{eV}$ and $E_2=2.5 \mathrm{eV}$ respectively. The ratio of maximum speeds of the photoelectrons in two cases is 2 . Work function of metal surface will be
