Presentation Transcript

  1. Sound waves are longitudinal waves • Loudness is connected to the amplitude • Larger amplitude means louder sound • Pitch is connected to frequency and wavelength • Higher pitch means • Higher frequency • Shorter wavelength • Graph air pressure vs. position to represent a sound wave.

  2. wavelength frequency Wave speed Wave speed does NOT depend on frequency and wavelength, although we can calculate it using f and λ.

  3. wavelength Length of spring # of antinodes

  4. Resonance

  5. Resonance occurs when an object vibrates at certain frequencies (particular to that object) and amplitudes much larger than the original vibrations occur. • Standing wave on a spring • Swing at the park
