Pengwuino said:Also, remember, coordinate axis are abstract concepts. When we see photons, they're flying off wherever the hell they feel like and we could arbitrarily assign an axis so that the photon is propagating along it.
It's up to you how you choose to align your coordinates. It will be easier if the photon moves parallel to one axis, but in general it will have velocity components of v = (vx, vy, vz) where[tex]Hippasos said:Ok, so in the case of photon we are always measuring the resultant c (coordinates fixed and aligned to the photon no matter howewer the observer assigns his/her coordinates. So obviously one shouldn't think resultant c = sum of all three velocity vector components (axes) in 3d space.
A photon in cartesian space refers to a particle of light that exists in three-dimensional cartesian coordinates. It is a fundamental unit of electromagnetic radiation and has properties of both a particle and a wave.
A photon is represented in cartesian space as a point in a three-dimensional coordinate system, with its position determined by its x, y, and z coordinates. Its direction of travel is represented by a vector pointing in the direction of its motion.
A photon's wavelength is inversely proportional to its position in cartesian space. This means that as the photon moves further away from its source, its wavelength will increase.
According to the principles of quantum mechanics, a photon can exist in multiple positions in cartesian space simultaneously. This is known as the wave-particle duality of light, where a photon can exhibit both particle-like and wave-like behavior.
A photon can interact with matter in cartesian space through a variety of processes, including absorption, reflection, and scattering. The type of interaction depends on the properties of the material and the wavelength of the photon.
