Six snapshot graphs of travelling harmonic waves are shown. They all have the same frequency but various amplitudes and wavelengths. Rank the waves by phase speed from slowest to fastest. E.g., if the slowest wave is B, the next faster one A, then C, and so on, enter BACDEF.

A)
0 0.5 11.5 22. 53
B)


C) D)


E) F)
