why does a standing wave appear to zero propagation
velocity ?
Prove that the group velocity of acoustic wave at Brillouin boundary is zero (or a standing wave), also prove that the group velocity of optical branch at point is also zero.
How can the standing wave have a velocity? A. It is the superposition of two traveling waves that have velocities. B. The standing wave is moving itself at a certain velocity. C. a standing wave can't have a velocity because it is standing D. a standing wave only consists of one traveling wave that is moving at a velocity

4. [2pt] Select ALL the correct definitions of the wavelength of a standing wave. E.g., if A and B are true and the rest are false, enter AB. The distance along the standing wave (in the direction of propagation) between repetitions of the wave shape. The distance along the standing wave (in the direction of propagation) from one node to the next node. The distance (in the direction of propagation) between adjacent crests. The distance (in the direction of propagation)...
