  • tells the amount of energy carried by a wave; how "loud" it is
    amplitude
  •  15
  • part in a longitudinal wave where the particles of the medium are close together
    compression
  •  10
  • highest point of a transverse wave
    crest
  •  5
  • The bending of a wave as it moves around an obstacle or passes through a narrow opening
    diffraction
  •  20
  • waves that do not need a medium to travel through (ex: visible light waves)
    electromagnetic waves
  •  15
  • The ability to do work or cause change
    energy
  •  10
  • The ability to do work or cause change
    energy
  •  15
  • the number of complete waves that pass a given point in a certain amount of time
    frequency
  •  15
  • Unit of measurement for frequency Hint: abbreviation Hz
    Hertz
  •  15
  • the interaction between waves that meet
    interference
  •  10
  • waves that move parallel to the direction in which the waves travel
    Longitudinal waves
  •  15
  • waves that require or need to travel through a medium (ex: sound waves)
    Mechanical waves
  •  15
  • the material through which a mechanical wave travels (solid, liquid, gas)
    medium
  •  10
  • part in a longitudinal wave where the particles of the medium are far apart
    rarefaction
  •  25
  • the bouncing back of a wave when it hits a surface through which it cannot pass.
    reflection
  •  10
  • The bending of a wave as it passes at an angle from one medium to another
    refraction
