Which wave has high frequency?

A: Waves with a higher frequency have crests that are closer together , so higher frequency waves have shorter wavelengths.19 Eyl 2019

The hertz measurement, abbreviated Hz, is the number of waves that pass by per second. For example, an “A” note on a violin string vibrates at about 440 Hz (440 vibrations per second).

Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies.
