Oscillations
Hooke's Law
The law applicable to the restoring force of Springs
Stress
What is the Restoring Force per unit area
Laplacian
del square
Compton effect
When a monochromatic beam of high frequency radiation such as X –
rays or Υ rays is scattered by a substance
• the scattered radiation is found to have a higher wavelength
glass
Example of a dielectric
A simple pendulum
Example of a damped oscillation
Youngs Modulus
What is Linear stress per linear strain
Divergence
outward flux per unit volume as the volume shrinks to zero about P’.
Wien’s displacement law.
States that the black-body radiation curve for different temperatures
will peak at different wavelengths that are inversely proportional to the
temperature.
transformer oil
an example of an insulating dielectric
Mach No.
The ratio of velocity of object in medium to sound in the same medium
Torsional Pendulum
A disc attached to a thin wire by a torsion
Gauss divergence theorem
helps us to transform a surface integral into volume integral.
Stefan’s fourth power law.
The area under each curve represents the total energy emitted at a
given temperature and it is found to be directly proportional to the
fourth power of the absolute temperature.
p-type semiconductor
doping of III group elements in an instrinsic SC
K=K1+K2
where K are the spring constants
What is the law of springs in parallel
Strain
change in length/original length
Gauss's law
describes the relationship between a static electric field and the electric charges that produce it.
Ultraviolet Catastrophe.
The failure of the Rayleigh – Jeans law to explain the spectrum beyond the
ultraviolet region towards the lower wavelength side of the spectrum is
referred as
INTRINSIC SC
fermi level at the centre of the energy gap
Sonic Boom
What is the sound associated with shock waves when an object travels through the air faster than the speed of sound.
Steel
High Youngs modulus
Stoke's Theorem
The line integral of a vector field over a loop is equal to the flux of its curl through the enclosed surface.
de Broglie Hypothesis
all moving objects have a particle and wave characteristics
Polar Dieletrics
Centre of +ve and -ve donot coincide
