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.
What else can I help you with?
What is meant by the half value layer of a homogenous beam?
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.
What is meant by the half value layer of a heterogenous beam?
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.
What is the difference between a hard beam and a soft beam?
A hard beam is one that contains a greater number of high energy photons than low energy photons.A soft beam is one that contains a greater number of low energy photons that high energy photons.During the filtration of a heterogenous beam (one that contains photons with different energies), low energy photons are removed from the beam, effectively "hardening" it.
What is the difference between a beam and a column?
A beam will be placed horizontally, a column will be placed vertically.
What is the difference between a column and a beam?
A beam will be placed horizontally, a column will be placed vertically.
How can you tell the difference between suspension colloid or solution?
Use the Tyndall Effect shine a light through it. If the light is scattered then it is colloidal. Both colloids and suspensions are heterogeneous. A solution will not show the beam through it's substance but the colloid will. The particles in the suspension will eventually settle at the bottom, showing that it is NOT a solution.
What is the difference between inverted beam and drop beam?
An inverted beam is a beam whose bottom is the same as the slab. A drop beam is a beam that is put under the structural member it supports.
What is the difference between a beam and a bar?
Beam can take transvesr loading and bar only axial loading
What is the difference between 9004 and 9007 headlights?
Just guessing but I imagine one is a high beam and one is a low beam.
What is the difference between a ridge board and a ridge beam?
A ridge board doesn't support rafters of the bridge whereas a ridge beam does.
What is the difference between a beam of light and a ray of light?
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
What is the difference between plinth and tie beam?
A plinth refers to the base that a column rests on. Tie beam refers to a beam that connects two or more columns, that acts as a stiffener.
