Wavelength = speed divided by frequency.
Speed = distance divided by time.
Therefore:
Wavelength = distance divided by (frequency x time).
You therefore need to know the frequency of the wave and the time it takes to travel in unit time.

The wavelength of a wave is the distance from the crest to the next crest of a wave, usually measured in metres. A wavelength is not a unit.
Wavelength (Apex)
Distance = time * average speed (velocity) Average speed = Distance/time
To find the acceleration if the time is not given, you will need to know the velocity and the distance. Then, use this equation: d = vt + (1/2)at2 to solve the problem by plugging in your numbers for the distance and the velocity.
