Presentation Transcript

  1. Waves Objectives: • Identify the properties and parts of a wave. • Compare transverse and longitudinal waves • and give examples of each.

  2. A wave is a disturbance in a medium that carries energy without a net movement of particles. A medium is what the wave is traveling through.

  3. Properties of waves: • Wavelength (λ) is distance between two identical parts of the wave. • Amplitude is maximum displacement from a neutral position. This represents the energy of the wave. *Greater amplitude carries greater energy. • Frequency is how often the particles of the medium vibrate when a wave passes through the medium. Units include waves/second or Hertz.

  4. Types of waves: • A transverse wave has the motion of the medium perpendicular to the movement of the wave pulse. • Examples: light waves, S-wave earthquake waves

  5. Types of Waves: • A longitudinal wave has the motion of the medium parallel to the movement of the wave pulse. • Examples: sound waves, P-wave earthquake waves

  6. Parts of a transverse wave:a. wavelengthb. crestc. trough

  7. Relationships: • Wavelength and frequency are inversely proportional. In other words, as one increase the other decreases. • Frequency and energy are directly proportional. In other words, if one increases, the other increases.
