WAVES

Information

- Examples of Superposition -


When two sound sources produce identical waves you might expect to hear a sound twice as loud. The situation is somewhat more complicated

IDENTICAL WAVES IN PHASE

IDENTICAL WAVES 162° OUT OF PHASE

IDENTICAL WAVES 18O° OUT OF PHASE

In the next example, two of waves of slightly different frequency interact to form a distinctive pattern called "beats". To clearly illustrate this process, different pictures represent different proportions of the total time you hear. The amount of each tone shown is indicated by a percent. of the total time.
