Transverse pulses

• Pulse


  A single disturbance that is propagated by a medium
• Transverse Pulse


  A pulse in which the displacement of the particles of the medium is perpendicular to the direction of the movement of the pulse
• Amplitude (A)


  Maximum disturbance of a particle from it's position of rest
• Pulse length


  Distance between the start and the ned of a pulse

  
• Pulse speed


  Distance by the pulse in one second
• formula for pulse speed:

  V=Pulse speed(m·s−1)

  x=distance covered(m)

  △t=change in time(s)

  $V=$$x/△t$
• constructive interference


  Occurs when the crest of two pulses meet each other on the same side of the rest position .Resulting amplitude is larger.

  
• Destructive Interference


  Occurs when the crest of one pulse and the trough of another pulse meet on opposite sides of the rest position.

  
• Superposition

  Is the algebraic sum of the the amplitudes of the two pulses that occupy the same space at the same time.
