Transferring of energy from one point to other generates wave. No material transfer occurs during this time. Reverse movement and interference of two sinusoidal wave trains of similar frequency and similar space generates standing waves. Standing wave involves a series of locations that are referred as nodes. These locations maintain similar spaced intervals when the wave amplitude is nil. During this point, two more waves add with reverse phase and neutralize each other. This specific activity occurs during the gap between a full wave length. The amplitude becomes highest between each pair of nodes. These are referred as anti-nodes. During this time, the two waves are includes in the same phase and strengthen each other.
