Question
A tuning fork, a glass tube, and a tall graduated cylinder are used to find the speed of sound in air. A tuning fork is struck and the length of the air column in the tube is changed by lifting it up and down in a graduated.
At the correct column length a loud musical note can be heard. This occurs because successive vibrations build up. This is known as
Responses
A diffraction.diffraction.
B harmonics.harmonics.
C instrumentation.instrumentation.
D resonance.

The correct answer is:
D) resonance.
Resonance occurs when the frequency of the tuning fork matches the natural frequency of the air column in the tube, leading to an amplification of the sound.
