Avalanche
Multiplication
Phenomenon
observed in gas filled detectors as per which when high electric field is
applied to anode wire, there occurs rapid multiplication of charges created in
primary ionization event near the wire where electric field intensity is high.
This process is called avalanche multiplication.
Average
Binding Energy
It is obtained by
dividing total binding energy of a nucleus by the number of nucleons in
nucleus. This energy is a measure of strength of nuclear bonding. The more
tightly bound the nucleons; the more stable the nucleus becomes and larger is
its binding energy.
Avogadro
Number
The number of
atoms or molecules in a mole of a substance is called Avogadro’s number.
Avogadro’s
Law
Equal volumes of
ideal gases existing under same conditions of temperature and pressure contain
equal number of molecules.
Avogadro’s
Principle
Whenever a body
is fully or partially submerged in a fluid, a buoyant force acts on the body
from the surrounding fluid. The force is directed upward and has a magnitude
equal to weight of fluid that has been displaced by body.
Axial
Chromatic Aberration
For an object at
infinity, the difference in focal length of a lens for the red and violet light
is called the axial chromatic aberration.
Axis
of Precession
The axis about
which the direction of rotation of body precesses is called as axis of
precession.
Axis
of Rotation
When a rigid body
undergoes a combined translation and rotational motion, there is at least a
point inside or outside the body whose velocity is zero. The body is said to
have pure rotation about that point. Then axis passing through that point and
perpendicular to plane of rotation is known as axis of rotation.
Axis
Vertical and
horizontal lines that make up quadrants of coordinate plane are referred to as
axis.
Azimuthal
Quantum Number
Azimuthal quantum
number is a quantum number, an integer assigned to an atomic orbital. It is
also called as “orbital angular momentum quantum number”. It helps in the
determination of the orbital angular momentum, which further helps in
elucidating the shape of the electron’s orbital. Azimuthal quantum number is the second set of the quantum numbers which
determines the quantum state of an electron and assumes integral values from 0
to 1.
