Question 1 Report

Which of the following instruments gives a pure note when sounded?
Answer Details
A pure note is a sound wave of a single frequency or pitch without any harmonics. The instrument that can produce a pure note when sounded is a tuning fork. A tuning fork is a small metal object with two tines that vibrate when struck against a surface. The vibration of the tines creates a pure tone with a specific frequency, which is determined by the size, shape, and material of the tuning fork. This pure tone makes a tuning fork useful in tuning musical instruments or testing the frequency response of audio equipment.
