A2 Unit G495 - Fields and Particles

Chapter 17 - Particle Physics

Title Description
History of particle physics This presentation looks at the history and discovery of some of the wide range of particles we now know.
Particle zoo This presentation explains some of the attempts at sorting the particle "zoo".
Hadron builder This "hadron builder" applet demonstrates how we can combine quarks to make hadrons and mesons.

Particle map This map groups the families of particles together with their composition and behavioural characteristics, and it should help you find your way through the confusing world of particles!
conservation rules Look at the simulation of beta decay, below.  Your teacher will explain how some inconsistencies observed in the early studies of beta decay can be explained using conservation rules, and the introduction of a new particle.

 

 

conservation rules link to Q10S, Q20S
   
Spectra and energy levels These questions Q150S look at the energy changes of electrons undergoing transitions between energy states, and how this leads to emission spectra.
Spectra and energy levels Suggested exam questions:
