Physics, G10 Transverse waves

• Pulse


  a single disturbance in a medium
• Transverse pulse


  a pulse in which the particles of the medium move at right angles to the direction of a motion of the pulse
• Transverse wave


  a wave in which the particles of the medium vibrate at right angles to the direction of motion of the wave. Succession of transverse pulses
• Wavelength


  distance between two successive points in phase

  
• Frequency


  number of wave pulses per second
• Period


  time taken for one complete wave pulse
• Amplitude


  maximum displacement of a particle from its rest position

  
• Crest


  highest point/peak of a wave

  
• Trough

  lowest point of a wave

  
• Constructive interference


  the phenomenon where the crest of one pulse overlaps with the crest of another to produce a pulse of increased amplitude

  
• Destructive interference


  phenomenon where the crest of one pulse overlaps with the trough of another, resulting in a pulse of reduced amplitude

  
• Compression


  a region of high pressure in a longitudinal wave

  
• Rarefaction


  a region of low pressure in a longitudinal wave

  
• Pulse length


  distance between start and end of pulse
• Equilibrium


  position of rest in a medium
