The wavelength of a proton, an electron and an α-particle moving with the same velocity are in the order: electron > proton > α-particle. How do you justify it?
The decreasing order of wavelength can be justified as, Wavelength is inversely proportional to mass i.e.
Thus, lesser the mass of particle, more is wavelength.
