WAVES

  1. 1. Submitted by: 5 Camille Joyce Bautista 6 Rica Rosario Borja 7 Iannah Blanche Braga 8 Ma. Cecillia Bukirin IV- St. Angela
  2. 3. What is a WAVE? <ul><li>A disturbance that travels through space and time, usually accompanied by the transfer of energy. </li></ul>
  3. 4. Crest and Trough: <ul><li>CREST – maximum value or upward displacement within a cycle. </li></ul><ul><li>TROUGH – minimum or lowest point in a cycle. </li></ul>
  4. 5. Crests and Troughs
  5. 6. Amplitude: <ul><li>Magnitude of change </li></ul><ul><li>Oscillation - repetitive variation </li></ul><ul><li>Measure of energy transferred </li></ul>
  6. 7. Equilibrium Position <ul><li>Also known as rest position. </li></ul>
  7. 8. Wavelength <ul><li>Distance between one point on a wave to the identical point in the next wave in the series. </li></ul><ul><li>(ex. Crest to crest, trough to trough) </li></ul><ul><li>Represented by greek symbol λ (lamda) </li></ul>
  8. 9. Characteristics of a wavelength: <ul><li>FREQUENCY - how often the particles of the medium vibrate when a wave passes through the medium </li></ul><ul><li>- temporal frequency </li></ul><ul><li>- Hertz (Hz) or cycles per second </li></ul><ul><li>PERIOD - the time needed for each particle to complete one full wave movement. </li></ul>
  9. 10. Types of waves: <ul><li>LONGITUDINAL WAVE- parallel to the direction of wave propagation. </li></ul><ul><li>- move backward and forward along the direction in which the wave is travelling. </li></ul><ul><li>TRANSVERSE WAVE- perpendicular to the direction of wave propagation. </li></ul><ul><li>- propagating from left to right. </li></ul><ul><li>- the particles do not move along with the wave </li></ul><ul><li>-oscillate up and down </li></ul>
  10. 11. Longitudinal and Transverse Waves
  11. 13. Classifications of wave: <ul><li>MECHANICAL - also known as material wave. </li></ul><ul><li>- needs a medium to travel. </li></ul><ul><li>- ex. ocean waves, and sound waves </li></ul><ul><li>- requires initial energy input. </li></ul><ul><li>Types: Transverse, Longitudinal, and Surface waves. </li></ul><ul><li>ELECTROMAGNETIC - require no medium but can travel through one. </li></ul><ul><li>-can travel not only through air and solid materials, but also through the vacuum of space. </li></ul>
  12. 14. Mechanical and Electromagnetic Waves
  13. 15. Electromagnetic Radiation <ul><li>Often abbreviated as E-M radiation or EMR </li></ul><ul><li>Form of energy that exhibits wave-like behavior as it travels through space. </li></ul><ul><li>Has both electric and magnetic field components. </li></ul><ul><li>Classified according to the frequency of its wave. </li></ul><ul><li>Carries energy and momentum that may be imparted to matter with which it interacts. </li></ul><ul><li>Increasing frequency and decreasing wavelength. </li></ul><ul><li>Consists of radio waves, micro waves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. </li></ul>
  14. 17. QUIZ: <ul><li>1. It is a disturbance that travels through space and time, usually accompanied by the transfer of energy. </li></ul><ul><li>2. It is also known as material wave. </li></ul><ul><li>3. It is a classification of waves that require no medium but can travel through one. </li></ul><ul><li>4. It is a type of wave that is perpendicular to the direction of wave propagation. </li></ul><ul><li>5. It is known as the rest position. </li></ul>
