1 Answer

Answer :

(3) Frequency Explanation: Pitch relates to the frequency, or how many times a second the particles vibrate. The distance between one wave and the next gives the wavelength. For sounds all travelling at the same speed, highfrequency (high-pitched) sounds have waves very close together.
