What do interference and diffraction have in common

  1. May 29, 2016 #1
    1. The problem statement, all variables and given/known data
    What do interference and diffraction have in common? We are learning the sound waves, but I would like to know all the things they have in common.

    2. Relevant equations
    x2-x1=λ/2 (contructive)
    3. The attempt at a solution

    The waves have the same frequency, after the process (interference or diffraction) they don't change; The waves keep having the same frequency (the source doesn't change); They have the same speed and length as they had before, because the environment doesn't change.Can you tell me something else they have in common?

    In the double slit experiment a single wave can diffract through both slits and interfere with itself.
