Dual Nature of ...

What wavelength must electromagnetic radiation have if a photon in the beam has the same momentum as an electron moving with a speed $$1.1\times 10^5$$m/s(Planck's constant $$=6.6\times 10^{-34}$$J-s, rest mass of electron$$=9\times 10^{-31}$$kg?

To increase de-Broglie wavelength of an electron from $$0.5\times 10^{-10}$$m to $$10^{-10}$$m, its energy should be _______.

If the de Broglie wavelength of a proton is $$10^{-13} m$$, the electric potential through which it must have been accelerated is

Five volts of stopping potential is needed for the photoelectrons emitted out of a surface of work function $$2.2\,eV$$ by the radiation of wavelength

The voltage applied to an X-ray tube is $$18 \ kV$$. The maximum mass of photon emitted by the X-ray tube will be

A particle of mass $$10^{-31},kg$$ is moving with a velocity equal to $$10^5 \,ms^{-I}$$ . The wavelength of the particle is equal to

The maximum kinetic energy of the photoelectrons emitted from a surface is dependent on the :

Einstein's photoelectric equation states that $$E_{k} = hv - \phi$$. In this equation $$E_{k}$$ refers to
