Answer:
The wavelength and frequency are inversely proportional to each other.
Step-by-step explanation:
Wavelength (λ): The distance between the two crusts or two troughs in the wave is known as the wavelength.
Frequency (f): It refers to the repetitions in a certain period of time.
These two are the key characteristics of a wave. These two are related as given below:


Here v = speed of the wave.
The wavelength and frequency are inversely proportional to each other.
