Description : The pitch of sound is measured by its (a) Intensity (b) Waveform (c) Frequency (d) Loudness
Last Answer : Ans:(c)
Description : The pitch of the sound is measured by its: (1) Intensity (2) waveform (3) Frequency (4) Loudness
Last 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.
