(i) A matter pulse is not electromagnetic in behavior.
(ii) Practical observation of matter waves is possible only when the de-Broglie wavelength is of the order of the size of the particles is nature.
(iii)Electron microscope works on the part of de-Broglie waves.
(iv)The medium speed of the matter waves can be larger than the speed of the light.
(v) The number of de-Broglie pulses connected with nth orbital electron is n.
(vi) Only those circular orbits around the nucleus are stable whose circumference is integral multiple of de-Broglie wavelength associated with the orbital electron.
When two particles tend to each other, their motion alters or their momentum modify because of their mutual interactions. This phenomenon is called as collision. During collision
