attractive force that holds the nucleons in the nucleus
2 of 16
antimatter
antiparticles that each have the same rest mass (equal & oppositely changed)
3 of 16
annihilation
when a particle and its antiparticle - destroy each other and become radiation
4 of 16
acceleration
change of velocity per unit time
5 of 16
critical angle
the angle of inidence of a light ray must exceed this for total internal reflection
6 of 16
diffraction
spreading of waves on passing through a gap
7 of 16
electromagnetic wave
electric & magnetic photon/ wavepacket that can travel through free space
8 of 16
electron capture
process in which the inner shell electron is captured y the nucleus
9 of 16
hadron
particles & antiparticles that can interact through the strong interactions ; can feel the strong nuclear force ; made up of quarks
10 of 16
hookes law
the extension of a spring is proportional to the force needed to extend it
11 of 16
leptons
fundamental particles ; don't feel the nuclear force
12 of 16
bayrons
B=1 ; protons (stable) & neutrons (decays) ; made of 3 quarks
13 of 16
mesons
B=0 ; all unstable ; pions (light) kaons ( heavy & more unstable) ; 1 quark
14 of 16
conserved
charge ; baryon number ; strangeness ; lepton number ; energy ; momentum
15 of 16
photoelectic effect
light ( greater than threshold frequency) shines on metal surface to emit electron ; free electrons on surface absorb energy = vibrate ; bond breaks& electrons released
