Rays and ray propagation
Ray model of light is based on an assumption
that light propagates along straight lines unless
its propagation is obstructed by obstacles.
According to this model, each point of a light
source emits
Wave motion
What is a wave?
Wave is a propagation of a disturbance of matter
This is a still picture of a disturbance. The points on the spring are oscillating in
the vertical direction. At the next instance a point at any given point will

Diffraction
Single-slit diffraction: minima
Diffraction pattern is characterized by a bright central maximum of intensity and a
sequence of weaker maxima separated from each other and the central maximum by
minima of intensity. Positions of the minima are
Inductance and ac circuits
Mutual inductance
When two circuits are nearby, the current in
one circuit creates a magnetic field, which is
not zero along the area occupied by the
second circuit. This field, therefore, creates
magnetic flux through the secon

Can the magnetic field create a current?
A constant (in time) magnetic field cannot create a
