Wavelength is the distance traveled by a wave pattern in the direction of propagation during one complete cycle as observed from a given point or the distance measured between consecutive corresponding points of a repeating wave pattern.
Frequency is the rate at which a wave pattern repeats as it passes by a designated point (the number of wavelengths that pass by) in a specified period of time, typically measured in cycles per second, f=c/s
Frequency and wavelength are
inversely proportional and when multiplied together equal the wave velocity, which in the case of an electromagnetic wave is the velocity of light in a vacuum or within the associated medium.
