प्रश्न
Out of electron and proton which one will have, a higher velocity to produce matter waves of the same wavelength? Explain it.
उत्तर
We have `lambda = h/(mv)`
Thus the equation signifies that in order to have the same wavelength the electron should have higher velocity as the mass of the proton is higher than that of the electron.
