Particles And Waves Flashcards
Three things you need to know about electromagnetic fields
Charged particles experience a force in an electric field
Electric fields exist around charged particles and between parallel plates
Electric fields are used to accelerate a charged particle
Three things you need to know about magnetic fields
Magnets cause magnetic fields
A moving charged particles produces a magnetic field
A magnetic field is used to deflect or guide the particles in a particle accelerator
The strength of the field _____ as we move away from the charge
Decrease
The closer together the field lines are the ________ the field is
Stronger
The field lines are_______between the parallel plates. This means the field strength is _________. What is this called
1.) equally spaced
2.) constant
Called a uniform field
Electric fields can be used in a number of different everyday activities including
The cathode ray tube
Spray painting
Photo coping
Pollution control
A stationary field creates an
Electric field
A moving charge creates an
Magnetic field
Definition of potential difference
I a measure of the work done in moving one coulomb of charge between two points in an electric field of the energy used up per coulomb of charge
What are particle accelerators used for
To investigate matter
Three main types of particle accelerators include
A source of particles
Beam. Pipes
Accelerating structures
A rapidly changing electric field
What is a fundamental particle
A fundamental partial is a particle that cannot be broken down into anything smaller than
Particles are split onto three parts
Leptons
Hadrons
Force mediating particles
Two types of hadrons
Baryon
Meason
In the standard model what does every particle have
Antiparticle
What is antimatter
Antimatter consists of particles are identical to their counterparts parts in every way apart from charge
What matter particle consists of quarks, up, down, strange, charm, top, bottom
Fermions
What matter particle is the electron muon and tall together with their neutrino
Leptons
What are the 4 force mediating particles
Photons- electromagnetic force
Graviton- gravitational force
W and Z boson- weak nuclear force
Gluon- strong nuclear force
What os an alpha particle
A helium nucleus
