charged particle

produces an electric field

magnetic field

region of space where a magnet is capable of exerting either repulsive/attractive force on magnetic material

electric field

generated when a charged particle/body accelerates

electromagnetic field

created by the interplay of changing electric & magnetic fields

electromagnetic wave

produced by accelerating charged particles oscillating about an equilibrium position

transverse wave

type of wave electromagnetic waves are

speed of light

all electromagnetic waves travel at this speed when in a vacuum

james clerk maxwell

considered the father of electromagnetic theory

3×10^8 m/s

value of speed of light

f / frequency

multiplied with wavelength to get speed of propagation

v / speed

= (frequency)(wavelength)

e / energy

= (planck’s constant)(frequency)

6.63×10^-34 Js

value of planck’s constant

ionizing radiation

sufficient energy to induce ionization

ionization

process of removing electrons from neutral atoms
