The half value layer of a homogenous beam is the thickness of the absorber that reduces the intensity of the beam to half the initial (starting) intensity.
The half value layer of a heterogenous beam is the thickness of the absorber that reduces the exposure rate to half the initial (starting) exposure.
beam
The neutral layer is a beam that supports a load is in the region where there is neither stretching nor compression.

A homogenous beam contains photons of the same energy (monoenergetic)Because the photons all have the same energy, their interactions with materials (such as the absorber) are all the same resulting in uniform attenuation.Heterogenous beams contain photons of different energies.Because the photons have different energies, their interactions with materials (such as the absorber) are different resulting in non-uniform attenuation.

Which way the antenna is pointing.
to focus light means to condense the energy of a light beam down to a smaller beam through refraction.
The value of Jim Beam decanters varies widely depending on the age and production limits.
The value of the 1973 Jim Beam VW Bug decanters is between $20 and $40 depending on the condition.
