Electromagnetism, Optics and Modern Physics
You learn about electric charge and the fields it makes, how circuits work, magnetism and how it links to electricity, then light as a wave, and finally the modern physics of relativity and the quantum world.
Class 1Electric charge and the electric field
The charge on things, and the field it creates around it.
Class 2Gauss's law and electric potential
A shortcut for fields, and the idea of voltage.
Class 3Capacitance and current
Storing charge, and charge on the move.
Class 4Direct-current circuits
How real circuits carry and use electricity.
Class 5Magnetic fields and forces
Magnetism, and the force it puts on moving charge.
Class 6Sources of magnetic field
How moving charges and currents make magnetism.
Class 7Electromagnetic induction
How a changing magnetic field makes electricity.
Class 8Electromagnetic waves
Light and radio as waves of electricity and magnetism.
Class 9Geometric optics: reflection and refraction
How light bounces and bends, and how lenses work.
Class 10Interference and diffraction
What happens when waves of light overlap.
Class 11Special relativity
How space and time change near the speed of light.
Class 12Quantum physics, atoms and the modern picture
The strange rules of the very small.
