Debroglie relationship

Q.7.6 Which biologically important entities should be treated as quantized (Hint consider the size and speed of the entity and apply the deBroglie relationship and then calculate /S.E/E). 

The constant k is also related to the wavelength through the deBroglie relationship, as shown in Equation (I 1.14). 

In order to more completely understand reciprocal space relative to real space defined by Cartesian coordinates, we need to first recall the deBroglie relationship that describes the wave-particle duality of matter ... 

DeBroglie, in the mid 1920s, proposed the idea that particles could be treated as waves by the relationship, X = h/mv. This equation related the mass (m) and velocity (v) of a particle to its wavelength (X) by using Planck s constant (h). 

Phonon dispersion expresses the phase relationship between different molecules in the lattice as they participate in the same mode. The repeat distance between molecules which vibrate totally in-phase is the phonon (deBroglie) wavelength, it is written in terms of the crystalline unit-cell dimensions and defines the characteristic momentum of the phonon, q. The...
