A slight loading of a tuning fork has the effect of
decreasing its amplitude
increasing its amplitude
decreasing its frequency
increasing its frequency
Correct answer is C
When the prongs of the tuning fork are loaded, it causes an increase in their inertia, thereby decreasing the frequency of the fork.
170ms-1
340ms-1
600ms-1
