However, the motion of an object along a surface with friction causes the production of heat, loss of mechanical energy, and general wear and tear on the object. Two objects in contact make microscopic connections at various points on their surface. Because ...

... difference between the scattered waves is dp sin./. When this pathlength difference is equal to an integer multiple of wavelengths dp sin./ D ml, the wavelets will arrive at the detector in phase (constructive interference), i.e. the total intensity will be twice that from a single particle. When ...
