Three difference between wavelength and frequency ?

Hi,
Wavelength: 
1.Wavelength measures the distance from one point of a wave to the same point on an adjacent wave.
2.Wavelengths are measured in nanometres.
3.The wavelength of the wave is inversely proportional to the energy of the wave.
Frequency:
1.Frequency represents how many waves are produced from the source per second.
2.Frequencies are measured in hertz or waves per second.
3.The frequency is linearly proportional to the energy of the wave.
Hope this Helps you.
