Standing Waves

  1. Jan 25, 2010 #1
    1. The problem statement, all variables and given/known data


    Am I right when i say, "Standing waves are produced by the superposition of two waves with the same amplitude and frequency, and opposite propagation directions".

    If I am then why would it not be, the same amplitude and direction of propagation, but different frequencies??

    Thanks for any help in advance.

    2. Relevant equations



    3. The attempt at a solution

    Stranding waves are formed by the reflection of the waves from a source. And the reflection does not change the frequency. A single source cannot produce two different frequencies. Two independent sources cannot produce standing waves.
