Qstnid -I-7-two Tuning Forks Vibrate With The Same Amplitude But The Frequency Of The First Is Double The Frequency Of The Second. Which Fork Produces More Intense Sound In Air? - 16: Sound Wave

#7
Two tuning forks vibrate with the same amplitude but the frequency of the first is double the frequency of the second. Which fork produces more intense sound in air?
Ans : We know that: intensity ∝ (amplitude)^2.
However, the intensity is independent of frequency. As the amplitude of the vibrating forks is the same, both the forks produce sounds of the same intensity in the air.
