I’ve seen one multiple educational videos that draw light as two orthogonal waves traversing through space. What is that trying to represent?What exactly is going up and down?
Furthermore, why do people often make the analogy that light acts like a ripple in a pond?
In: Physics
A moving electric field produces a magnetic field at right angles to it. A moving magnetic field induces an electric field perpendicular to it.
Each feeds each other moving electric field —> moving magnetic field —> moving electric field.
It’s the original (and only) bootstrap process.
