Alloying: When an impurity atom of a different size compared to the host atom is placed into the crystal lattice, the impurity atom distorts the resin around it, either by pushing the host atoms farther away, or by pulling them in, as depicted. The cross section that scatters the electron is the lattice region that has been elasticity distorted by the impurity (the impurity atom itself and its neighbouring host atoms), so that in this zone, the electron suddenly experiences a force due to sudden change in PE. This region has a large scattering event from impurity only. We define τt as the mean time between scattering events arising from thermal vibrations alone and as the mean time between scatterings events arising from collisions with impurity alone. In, general an electron may be scattered by both processes, so effective mean time τ between any which scattering events will be less than the individual scattering time.
What are the sources of dispersion in optical fibers? Sources of Dispersion into Optical fibers: The key sources of dispersion of pulses within optical fibers can be catego
There are imaginary lines or path of the field in the given direction. The lines of force are assumed to make a closed path beginning from N pole and ending at S pole with no loss.
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
A proton and an alpha particle pass by the gap of a strong magnet. If both particles have the similar initial velocity, how many times greater will the defection of the proto
DISPLACEMENT: The change in the position of a body from its starting position to its final position is known as displacement. It is denoted by d ?.
