- In polar coordinates, the gradient of a scalar function is a vector that represents how much the function changes in each coordinate direction. The θ-basis vector originally has a length of r, meaning that its length changes as you go further away from the origin1. The superposition of two counterpropagating beams of light with orthogonal polarizations creates a gradient where the polarization varies in space. The gradient depends on which type of polarization is used2.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.The gradient of a scalar function is essentially a vector that represents how much the function changes in each coordinate direction. Now, in polar coordinates, the θ-basis vector originally has a length of r (not the unit vector in the above formula), meaning that its length changes as you go further away from the origin.profoundphysics.com/gradient-in-different-coordina…The superposition of two counterpropagating beams of light with orthogonal polarizations creates a gradient where the polarization varies in space.
