A particle is dropped from a height H. The de Broglie wavelength of the particle as a function of height is proportional to

The wavelength of a photon needed to remove a proton from a nucleus which is bound to the nucleus with 1 MeV energy is nearly

Consider a beam of electrons (each electron with energy E₀) incident on a metal surface kept in an evacuated chamber. Then Chapter Eleven

Consider Fig. 11.7 in the NCERT text book of physics for Class XII. Suppose the voltage applied to A is increased. The diffracted beam will have the maximum at a value of that

A proton, a neutron, an electron and an α-particle have same energy. Then their de Broglie wavelengths compare as
