Question 1 Name and discuss any two aspects of sound. (8) Pitch: Pitch refers to the highness or lowness of a sound and is determined by the frequency of the sound waves. Higher frequencies result in higher-pitched sounds, while lower frequencies produce lower-pitched sounds. For example, a whistle produces a high-pitched sound, while a bass drum produces a low-pitched sound. Pitch is measured in Hertz (Hz), with higher frequencies having a greater number of cycles per second....
