A proton and a deuteron are accelerated through the same accelerating potential. Which one of the two has the greater value of de-Broglie wavelength associated with it, and Give reasons to justify your answer.
de-Broglie wavelength of a particle depends upon its mass and charge for same accelerating potential, such that
Mass and charge of a proton are mp and e respectively, and, mass and charge of a deutron are 2mp and e respectively. where, e is the charge of an electron
Thus, de-broglie wavelength associated with proton is`sqrt2` times of the de-broglie wavelength of deutron and hence it is more.
