Convection current - motion of a fluid as result of differences in fluid density

Convection current - motion of a fluid as result of differences in fluid density

Coulomb’s law - the electric force between two point charges is proportional to the product of the charges and inversely proportional to the square of their separation

Crest - point on a wave of maximum displacement

Critical angle - the angle of incidence for which the angle оf refraction is a right angle

Critical mass - the smallest mass of fissionable material that can sustain fission reactions

Decay constant - the probability per unit time for a nucleus to decay

Decay series - the sequence of decays that occurs until a radioactive element reaches a stable nuclide

Destructive interference - the superposition of two identical waves that arrive at a point 180° out of phase

Dielectric - insulator that shows charge polarisation
