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.

The half value layer for lead is approximately 0.5 mm for a standard diagnostic x-ray beam. This means that half of the x-ray beam intensity is absorbed by 0.5 mm thickness of lead. Lead is commonly used as a shielding material in radiology to protect against radiation exposure.
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.
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.

A compact disc (CD) stores data by using microscopic pits and lands in its middle layer called the polycarbonate layer. These pits and lands are read by a laser beam in order to retrieve the stored information.
