Frequency and wavelength are proportional.

directly

inversely

uniformly

Inversely proportional.

The distance between two wave troughs is considered as wavelength whereas the number of wave crests passing over the origin every second is termed as frequency. The former is denoted by symbol known as lambda whereas the latter is denoted by ''.

We can utilize this relationship to compute the wavelength or recurrence of any electromagnetic wave on the off chance that we have the other estimation. Simply separate the speed of light by whichever estimation you have and afterward you have the other.  

Frequency = Speed of Light/Wavelength  

f = c/λ  

Wavelength = Speed of Light/Frequency  

λ = c/f  

Above given equation demonstrates that wavelength and frequency are inversely proportional to each other which means that higher the frequency, shorter will be the wavelength and vice versa.
