To further explore what this equation means, consider four sets of identical waves that move in the x direction. A photo is taken of each wave at time ttt and is displayed in the figures below. Rank these sets of waves on the basis of the maximum amplitude of the wave that results from the interference of the two waves in each set. Rank from largest amplitude on the left to smallest amplitude on the right. To rank items as equivalent, overlap them.
