  1. Waves Part 2

  2. Amplitude is related to the energy carried by a wave. () • The greater the amplitude of a wave, the more energy it carries. Amplitude and Energy

  3. Amplitude of Transverse Waves • The higher the wave, the more energy it carries. • Amplitude = The distance from the crest or trough to the rest position of the medium. Rest Position

  4. Amplitude of Compressional Waves • More tightly packed at the compressions means a greater amplitude

  5. Which wave has more energy?

  6. Frequency and Energy The frequency of a wave also determines the energy of a wave. The higher the frequency, the higher the energy of a wave.

  7. Which wave has more energy?

  8. Speed • Speed describes how fast the wave moves. • Speed is frequency (f) times wavelength (l) Speed (m/sec) Wavelength (m) Frequency (hz)

  9. Medium and Wave Speed Only the medium determines the speed of a wave. If the frequency of a wave is changed, then the wavelength changes so that remains constant.
