How does the force at which you hit the tuning fork relate to compressions and rarefactions of the sound wave? How does the force at which you hit the tuning fork relate to compressions and rarefactions of the sound wave? Both the amount of compression and rarefactions are increased with greater force applied to the tuning fork. The amount of compression decreases and the amount of rarefactions increase with greater force applied to the tuning fork. Compressions and rarefactions are not related to the amount of energy in sound vibrations.

That's correct!

Sorry, that’s not correct. As force increases, the amplitude of the sound wave is higher (greater compression and rarefaction) resulting in a higher amplitude.
