Chi
square Test
It is also called
goodness of fit test. The test allows testing hypothesis using nominal or
ordinal data. It does this by testing whether one set of proportions is higher
or lower than you would expect by chance. Chi square summarizes the discrepancy
between the observed and expected frequencies.
Choke
Coil
An inductance
coil used in alternating current circuits to limit the current without
dissipation of power is called as choke coil. Choke consists of a pure copper
wire wounded on a rectangular soft iron to minimize eddy currents and
hysteresis losses.
Chord
A line segment
connecting two points in a circle.
Chromatic
Aberration
The type of
aberration found in images formed by lenses when the source of light is not
monochromatic. Formation of a colored and blurred image of white object by a
lens due to dispersion is called chromatic aberration.
Chromosphere
It is narrow
layer above Photosphere. It constitutes gaseous layer. It can’t be seen by naked
eye and usually appears as narrow, red ring around sun.
Circle
It is a geometrical
plane figure which is locus of all points equidistant from central point.
Circular
Motion
It is motion of an object in a circle at a constant speed.
Circular
Polarization
Light is said to be circular polarized if two electromagnetic
waves are perpendicular to each other having same amplitude and phase
difference of 90o.
Circularly
Polarized Light
When two plane
polarized light waves superpose with a definite phase difference, the resultant
light vector revolves with fixed amplitude in a plane perpendicular to
direction of propagation of light. In some special cases, the tip of light
vector describes a circle. This light is called circularly polarized
light.
Circumference
Perimeter
of circle is called as circumference.
Cladding
Process of covering fuel bundles in nuclear
reactors to avoid direct physical contact to the moderator or coolant is called
as cladding. The cladding material is transparent to the thermal neutrons and
withstands very high temperatures.
Classical Physics
Classical physics
is the branch of physics which depends on Newton’s laws of motion. Classical
physics is usually divided into several branches, each of which deals with a
group of related phenomena. Mechanics is the study of forces and their effect
on matter. Dynamics is the study of change in motion because of force.
Hydromechanics is the mechanics of fluids; that is, of liquids and gases.
Hydromechanics is also known as fluid mechanics. Statics deals with how force
affects bodies in constant motion and moving in a constant direction. Optics is
the study of the behavior of light. Thermodynamics is the study of heat, and
how heat energy
is stored, transmitted, and converted to other forms of energy. Acoustics is
the study of sound. The study of electricity and magnetism also forms a branch
of classical physics.
Clausius
Clapeyrons Equation
Thermodynamics
equation which tells us that the change in melting or boiling point with the
change in pressure in terms of latent heat of fusion or latent heat of vaporization.
It is expressed as
T(dP/dt)=L /T(V2-V1)
‘T’
is Constant Temperature; ‘P’ is Pressure
‘L’ is Latent heat at const temperature. V2
and V1 are specific volumes of substance before and after change in
state without change in temp.
If V2
> V1; Melting point increases with increase in pressure and
boiling point increases with increase in pressure.
If V2<V1; Melting
point decreases with increase in pressure.
Clausius
Mossotti Relation
It is the
relation between macroscopic dielectric constant and microscopic polarization.
Clausius
Statement of Second Law of Thermodynamics
It is impossible
for a self acting machine, to transfer heat continuously from one body to
another at high temperature.
Clausius
Theorem
The sum of
quantities of heat transfer during the isothermal change divided by absolute
temperature of isothermal in a reversible cycle is zero.
Cleavage
For most brittle crystalline
materials, crack propagation corresponds to the successive and repeated
breaking of atomic bonds along specific crystallographic planes. This
phenomenon is called as cleavage.
Clebsch-Gordon Coefficient
The Clebsch-Gordan coefficients are sets of numbers that arise in angular momentum coupling under the laws of quantum mechanics.
