Sound Production And Measurement

Pitch is a measure of the frequency of a sound wave, which refers to how high or low a sound is perceived. Hertz is the unit used to measure frequency, specifically the number of cycles or vibrations per second. Therefore, hertz is the correct answer for measuring pitch.

The horizontal arrow in this context most likely represents the wave length or pitch. Wave length refers to the distance between two consecutive points in a wave that are in phase, while pitch refers to the perceived frequency of a sound. Both wave length and pitch can be represented visually using a horizontal arrow, making them the most suitable options for the correct answer.

Sound is measured in terms of volume and pitch. Volume refers to the loudness or softness of a sound, while pitch refers to the highness or lowness of a sound. These two factors are used to quantify and describe the characteristics of sound. Volume is determined by the amplitude of the sound wave, with higher amplitudes resulting in louder sounds. Pitch, on the other hand, is determined by the frequency of the sound wave, with higher frequencies producing higher pitched sounds. Therefore, volume and pitch are the correct measurements for sound.

The vertical arrow in this context is most likely referring to the vertical axis on a graph or diagram. In terms of sound waves, the vertical axis represents the amplitude or volume of the wave. Amplitude refers to the magnitude or intensity of the wave, while volume is a subjective perception of the loudness or softness of the sound. Therefore, the vertical arrow would indicate the level of amplitude or volume in the given context.
