1. The problem statement, all variables and given/known data If a standing wave is produced by two identical waves travelling in opposite directions, is the wavelength of the resultant wave simply the wavelength of the original wave? 2. Relevant equations ysin(kx)cos (wt) 3. The attempt at a solution I'm pretty sure it produces a wavelength of the original wave because A standing wave requires that the nodes and antinodes remain in the same place, but I want to make sure. Please help!
