So, if you have a mirror and a particle and the source emits one photon, which one hits the particle, the photon or it's reflection in the mirror or both?
The discussion revolves around the behavior of a photon emitted towards a particle and its interaction with a mirror. Participants explore concepts related to reflection, interference, and the nature of photons in quantum mechanics, with references to experimental setups like Lloyd's mirror and Fresnel's mirrors.
Participants express differing views on the nature of photon reflection and interference, with no consensus reached on whether both the photon and its reflection can simultaneously interact with a particle.
Discussions involve assumptions about the behavior of photons as waves and the implications of quantum mechanics, including the concept of "which-way" information and the conditions under which interference occurs.
jtbell said:Are you thinking of something like the Lloyd's mirror interference setup? The source and its image in the mirror act like the two slits in the usual two-slit interference setup. A single photon follows either one path or the other. If there is no "which-way" information, the two paths interfere and you build up an interference pattern on the screen as you send more and more photons through the system, one after the other.
