Wave and its properties

  1. 1. PARTS OF THE WAVE
  2. 2.  CREST - the highest point of the wave. TROUGH - the lowest point of the wave. AMPLITUDE - is the displacement from the resting position to the highest (or lowest) point of the wave. WAVELENGTH – is the distance from one point to the next identical point of the wave.
  3. 3.  FREQUENCY – describes how often a vibration occurs. It also specifies how many complete vibrations occur at a given time (usually one second). 1 1F = or T Period* The SI Unit of frequency is the HERTZ (Hz) , equivalent to one cycle per second.
  4. 4.  PERIOD – is the time needed to complete one vibration. 1 1T = or F Frequency
  5. 5.  WAVE SPEED - is the rate at which the wave travels through a particular point. Wave speed = Frequency x Wave length or wavelengthWave speed = period
  6. 6.  WAVELENGTH – distance from crest to crest.The wavelength λ of a sinusoidal waveform traveling at constant speed v is given by: v λ = fwhere v is called the phase speed (magnitude of the phase velocity) of the wave and f is the waves frequency.
  7. 7.  LOUDNESS - physiological sensation that varies from one person to another. It depends on the sense of hearing. INTENSITY (I) - depends on the amplitude of pressure variations within the sound waves. The unit used for sound intensity level (B) is decibel (dB) , named after Alexander Graham Bell. QUALITY – enables to identify the source of sound because tones differ from one another. PITCH – refers to the highness or lowness of a tone. It is related to frequency.
  8. 8. REFLECTION OF WAVEa.) REFRACTED- when wave travel from one medium to another.b.) DIFFRACTED- when wave pass through a narrow opening and interfere when they interact with other wave.
  9. 9. TRANSVERSE WAVE The vibrational direction of the particles in the medium is up and down perpendicular to the direction of the wave.
  10. 10. LONGITUDINAL WAVE The vibrational direction of the particles of the medium is parallel to the direction of the wave.
