Waves as Carrier of Energy

• Vibration is produced whenever an object or a particle moves back and forth
• The vibration may or may not require some material, called a medium,

  for the wave to travel.
• A wave is a disturbance or a vibration that transfers energy through matter or space.
• the initial horizontal position of the rope is considered as the equilibrium

  position.
• A transverse wave is a type of wave where the motion of the particles in the medium is perpendicular (or at a right angle) to the direction the wave travels.
• A wave pulse is a single disturbance that travels along the medium.
• Once there is a series of wave pulses traveling in a medium at the same rate, a periodic wave is produced.
• that a crest is the highest point in a transverse wave
• a trough is the lowest point.
• amplitude is the maximum distance between the equilibrium

  position and the crest or trough of a wave.
• the wavelength is the distance between any successive identical parts of a wave.
• The longitudinal wave is a wave where the motion of the

  particles in the medium is parallel to the direction the wave travels.
• Some parts of the Slinky are closely spaced, this part is called compression.
• those parts that are stretched are called rarefactions.
• A mechanical wave is a disturbance that requires a medium to transfer energy from one place to another.
• A sound wave is also a good example of a mechanical wave.
