  • What is a WAVE?
    • A disturbance that travels through space and time, usually accompanied by the transfer of energy.
  • Crest and Trough:
    • CREST – maximum value or upward displacement within a cycle.
    • TROUGH – minimum or lowest point in a cycle.
  • Crests and Troughs
  • Amplitude:
    • Magnitude of change
    • Oscillation - repetitive variation
    • Measure of energy transferred
  • Equilibrium Position
    • Also known as rest position.
  • Wavelength
    • Distance between one point on a wave to the identical point in the next wave in the series.
    • (ex. Crest to crest, trough to trough)
    • Represented by greek symbol λ (lamda)
  • Characteristics of a wavelength:
    • FREQUENCY - how often the particles of the medium vibrate when a wave passes through the medium
    • - temporal frequency
    • - Hertz (Hz) or cycles per second
    • PERIOD - the time needed for each particle to complete one full wave movement.
  • Types of waves:
    • LONGITUDINAL WAVE- parallel to the direction of wave propagation.
    • - move backward and forward along the direction in which the wave is travelling.
    • TRANSVERSE WAVE- perpendicular to the direction of wave propagation.
    • - propagating from left to right.
    • - the particles do not move along with the wave
    • -oscillate up and down
  • Longitudinal and Transverse Waves
  •  
  • Classifications of wave:
    • MECHANICAL - also known as material wave.
    • - needs a medium to travel.
    • - ex. ocean waves, and sound waves
    • - requires initial energy input.
    • Types: Transverse, Longitudinal, and Surface waves.
    • ELECTROMAGNETIC - require no medium but can travel through one.
    • -can travel not only through air and solid materials, but also through the vacuum of space.
  • Mechanical and Electromagnetic Waves
  • Electromagnetic Radiation
    • Often abbreviated as E-M radiation or EMR
    • Form of energy that exhibits wave-like behavior as it travels through space.
    • Has both electric and magnetic field components.
    • Classified according to the frequency of its wave.
    • Carries energy and momentum that may be imparted to matter with which it interacts.
    • Increasing frequency and decreasing wavelength.
    • Consists of radio waves, micro waves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
