1.	An electron or a proton which one will have a higher velocity to produce matter waves of the same wavelength? Explain it.
Answer» Solution :From de-Broglie equation, wavelength `LAMBDA = H/(mv)` for same wavelength with two different particles, (ie) electron and proton `m_1v_1 = m_2v_2` (h is constant) LESSER the MASS of the PARTICLE, greater will be the velocity. Hence electron will have higher velocity.
