Schrodinger Wave Equation
Infinite Potential Well
Heisenberg's Uncertainty
Principle
A potential well is a potential energy
function V(x) that has a minimum.,
Schrodinger Equation for a particle in well
Dual Nature of Matter
De Broglie`s Hypothesis
Wave Packet Concept
DEFINITION : If a light wave can act as a wave
sometimes and as a particle at other times, then
particles such as electrons should also act as
waves at times. This is known as de Broglie
hypothesis.
De Broglie`sEquation,
DEFINITION : The superposition of several
waves having same amplitude and slightly
different frequencies or wavelengths is known as
wave packet
Group Velocity : The velocity with which the
wave packet propagates is called the group
velocity.
Phase Velocity : The velocity with which the
plane of equal phase travels through a medium is
known as the phase velocity.
STATEMENT : It
is impossible to know simultaneously and with
exactness both the position and momentum of a
microparticle.
Expression :
APPLICATIONS :
1. To find the expression for Bohr's Orbit and
Energy.
2. To find the position of Particle in a Box.
3. It confirms the non-existance of electron
inside nucleus.
Born's Interpretation :
The square of the magnitude of the wave
function |Ψ|^2evaluated in a particularregion
represents the probability of finding the
particle in that region.
