Can Multiple Waves Interfere in a Single Medium?

[mad_max]

can more than two waves interfere in a given medium?

i'm guessing yes. b/c 2 drops in water cause a lot of waves and they can interfere each other, maybe

Of course, you can get all kinds of wild interactions. A lot of the optical effects we see are due to interferance between many electromagnetic waves going in every which direction. Look at The Feynman Lectures on Physics Chapters 29 and 30 for a good discussion on the interferance of waves from multiple sources.
