wavelength is 

• the distance between two consecutive points on a wave that are moving in the same way.
• a disturbance that repeats regularly in space and time and that transmit energy from one place to the other with no transfer of matter
• energy from the wind that causes a turbine to turn in order to generate electricity
• the vertical force exerted by a mass as a result of gravity
