  1. Wave Motion

  2. A wave is a disturbance that carries energy through matter or space. What Is a Wave?

  3. What Is a Wave?

  4. Most waves travel through a medium. • medium:a physical environment in which phenomena occur • Air – Water - Etc • mechanical wave:a wave that requires a medium through which to travel • examples: sound waves, water waves What Is a Wave?

  5. Electromagnetic waves do not require a medium. • electromagnetic wave: a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light • examples: visible light waves, radio waves What Is a Wave?

  6. Electromagnetic Waves

  7. Waves transfer energy. • Small or Large amounts Depending on Type and Size • Tsunamis carry enough energy to cause damage to coastal towns. • The energy of normal ocean waves breaks up rocks into pieces to form sandy beaches. What Is a Wave?, continued

  9. Energy may spread out as a wave travels. • When sound waves travel in air, the waves spread out in spheres. • As the waves travel outward, the spherical wave fronts get bigger, so the energy spreads out over a larger volume. What Is a Wave?

  10. How are waves generated? • Most waves are caused by vibrating objects. • The sound waves produced by a singer are caused by vibrating vocal cords. • Electromagnetic waves may be caused by vibrating charged particles. • For mechanical waves, the particles in the medium through which the wave passes vibrate, too. Vibrations and Waves

  11. The mechanical energy of a vibrating mass-spring system changes form. • This type of vibration is called simple harmonic motion. Vibrations and Waves

  12. A wave can pass through a series of vibrating objects. • The disturbance travels down the row as energy is transferred from one mass to another. • Wave particles move like masses on springs. Vibrations and Waves

  13. A transverse wave is a wave in which the wave motion is perpendicular to the particle motion. A longitudinal wave is a wave in which the wave motion is parallel to the particle motion. Transverse and Longitudinal Waves

  14. Transverse waves have perpendicular motion. • transverse wave: a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling

  15. Transverse Wave

  16. Longitudinal waves have parallel motion. • longitudinal wave: a wave in which the particles of the medium vibrate parallel to the direction of wave motion

  17. Longitudinal Wave

  18. Waves have crests and troughs or compressions and rarefactions. crest:the highest point of a wave trough: the lowest point of a wave compressions:the crowded areas of a longitudinal wave rarefactions: the stretched-out areas of a longitudinal wave

  19. The particles in a surface wave move both perpendicularly and parallel to the direction in which the wave travels. • surface waves:waves that occur at the boundary between two different mediums, such as water and air Surface Waves

  20. Formation and Movement of Ocean Waves
