Corpuscular
Theory
The theory,
originally proposed by Newton, and revived with the development of the quantum
theory that light consists of a stream of particles.
Corrosion
Deteriorative
loss of a metal as a resultant of dissolution to environmental reactions.
(or)
Destruction
of metal by getting converted into oxide.
Cosmic
Background Radiation
The secondary
particles in cosmic rays such as muons, pions, neutrinos etc reaching earth,
are called as cosmic background radiation.
Cosmic
Rays
High
energy particles that bombard earth from anywhere beyond its atmosphere are
called as cosmic rays. They mainly originate from supernovae. They include
i) Galactic
cosmic rays coming from outside solar system, the composition of which is
mainly protons, Helium nuclei and heavy ions.
ii) Anomalous
cosmic rays are those coming from interstellar space at edge of heliopause.
iii)Solar
energetic particles associated with solar flares and other energetic solar
events.
Cosmology
Branch of astronomy which deals with general structure,
evolution, and characteristics like space, time etc.
Cosmotron
It was first particle
accelerator to impart kinetic energy in the range of GeV to particles
especially protons. The maximum energy attained by accelerated particle is
about 3.3 GeV. The device was at Brookhaven national Laboratory. It was used to
observe various Mesons previously seen only in cosmic rays, and to make first
discoveries of heavy, unstable particles.
Cotangent
In a right angled
triangle, the cotangent of an angle is “the length of the adjacent side
divided by the length of the opposite side”.
Coulomb
Force
See electrostatic force.
Coulomb
It is the SI unit
of electric charge.
Coulombs
Law
The electric
forces exerted on each other by two point charges separated by a distance are
proportional to product of magnitude of two charges and inversely proportional
to the square of distance of separation. The forces act along the line joining
the two charges.
Couple
A pair of equal
and unlike parallel forces acting at different points on rigid body is called
Couple.
Covalent
Bond
Covalent bond is
formed by sharing of pairs of valence electrons between “like” atoms. Covalent
bonding is also known as homo polar or electron pair bonding
Covariant
Equation
An equation which
has the same form in all inertial frames of reference; that is, its form is
unchanged by Lorentz transformations.
CPT
Invariance Law
All physics interactions are invariant
under combined operation CPT irrespective of order of operations.
Creep
The time
dependent permanent deformation that occurs under stress is called as creep.
Critical
Angle
It is the angle
of incidence of ray travelling from denser to rarer medium, for which angle of
refraction becomes 90 oC.
Critical
Damping
The minimum
amount of viscous damping that results in a displaced system returning to its
original position without oscillation.
Critical
Magnetic Field
Maximum magnetic
field which when applied to a superconductor below transition temperature, the
superconducting property is destroyed.
Critical
Mass
It is the minimum
quantity of fissile material which reduces loss of neutrons escaping through
geometric boundaries, thus making the mass capable of sustaining fission chain.
Critical
Pressure
The pressure
required to liquefy the gas at critical temperature is called critical pressure
of gas.
Critical Temperature(Superconductivity)
See transition temperature.
