Vedclass · Answer

(A) According to the de Broglie relation,the wavelength $\lambda$ is given by $\lambda = h / p = h / (mv)$,where $h$ is Planck's constant,$m$ is the mass,and $v$ is the velocity.Since the speed $v$ is constant for all particles,the wavelength $\lambda$ is inversely proportional to the mass $m$ of the particle $(\lambda \propto 1/m)$.Comparing the masses: $m_{	ext{electron}} Since the electron has the smallest mass,it will have the longest wavelength.

If travelling at equal speeds,the longest wavelength of the following matter waves is that for a :
