What is the diffrance between wavelength and frequency

Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength. 

Wavelength- The measure of distance between sound waves, it's used to measure the length of a sound wave

Frequency- The measure of time and how the sound waves themselves occur 

There are no metaphors.
