  • Superposition
    • Definition: When two or more waves meet at a point, the net displacement at that point is = to the algebraic sum of the individual displacements due to the waves
    • Interference
      • Is the variation of wave amplitude that occurs when waves of the same or different frequency come together.
        • The interference of waves causes the medium to take on a shape that results from the net effect on the two individual waves upon the particles of the medium
          • Constructive
            • Occurs when the path difference is an integer and when the waves meet in phase
              • Destructive
                • When waves do not meet in phase, and the path difference is not an integer
                • If light was the wave in question, then when destructive interference occurs, the light would not be seen
            • If it was a light wave in question, when constructive interference occurs, you would see the light much more brighter
