What happens when frequency is high?

The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength , while waves with a low frequency have a longer wavelength.

The higher the number is, the greater the frequency of the waves . The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing afixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency waves with the same amplitude.19 Eyl 2019

In physics, the term frequency refers to the number of waves that pass a fixed point in unit time . It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter . As the frequency decreases, the wavelength gets longer.
