Answer 2

If a sound's pitch is high, its source is vibrating quickly. (Option b)

• In simple language, the term pitch is used to describe the loudness of a sound, whether it is high or low.
• But the pitch is not the same as loudness.
• If loudness is related to the sound wave's amplitude, then the pitch is related to the sound wave's vibration frequency.
• The number of vibrations occurring in one second is the vibration's frequency.
• If there are more vibrations taking place in one second, then the pitch is said to be very high.
• If there are only a few vibrations taking place in one second, then the pitch is low.
