  • Electromagnetic Wave
    A wave consisting of oscillating electric and magnetic fields, propagating through space.
  • Sinusoidal Wave
    A wave with a shape that can be described by a sine function, representing periodic oscillations.
  • Electric Field
    A field around charged particles that exerts force on other charges, oscillating in a wave.
  • Magnetic Field
    A field produced by moving electric charges, oscillating perpendicular to the electric field.
  • Propagation
    The movement or transmission of waves through a medium or space.
  • Transverse Wave
    A wave where oscillations are perpendicular to the direction of wave travel.
  • Amplitude
    The maximum extent of a wave's oscillation, measured from its equilibrium position.
  • Angular Frequency
    A measure of how many radians a wave oscillates per unit time.
  • Wave Number
    A measure of spatial frequency, defined as 2π divided by the wavelength.
  • Wavelength
    The distance between successive crests of a wave, determining its spatial period.
  • Period
    The time taken for one complete cycle of a wave to pass a given point.
  • Frequency
    The number of complete oscillations a wave makes per unit time.
  • Speed of Light
    The constant speed at which light waves propagate in a vacuum, approximately 299,792,458 m/s.
  • Nanometer
    A unit of length equal to one billionth of a meter, often used to measure wavelengths.
  • Blue Light
    A type of visible light with a wavelength around 450 nanometers, part of the electromagnetic spectrum.
