In an electron microscope
An electron beam is accelerated by a potential difference V to hit a metallic target to produce X−rays. It produces continuous as well as characteristic X−rays. If λmin is the smallest possible wavelength of X−ray in the spectrum, the variation of logλmin with log V is correctly represented in :

An electron from various excited states of hydrogen atom emit radiation to come to the ground state. Let λn,λg be the de Broglie wavelength of the electron in the nth state and the ground state respectively. Let ⋀n be the wavelength of the emitted photon in the transition from the nth state to the ground state. For large n, (A, B are constants)
