AI Thread Summary
Particle-antiparticle annihilation results in the production of photons, specifically in the gamma region of the electromagnetic spectrum. Photons can be generated from various sources, not just from vibrating electrons or atomic transitions. Any accelerating charge, including protons, can produce electromagnetic radiation. Most nuclear reactions are associated with gamma ray production. Thus, photons are produced through multiple mechanisms beyond just electron vibrations.

are photons only generated from vibrating electrons? only from atomic transitions?
 
Science news on Phys.org
Any accelerating charge produces electromagnetic radiation. This can be protons too (as during production of gamma rays).
 
Most nuclear reactions involve gamma ray production.

Thread 'Simple math model for a Particle Image Velocimetry system'

Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
