A homework question I'm struggling with as we've done nothing on it in class so I don't know how we're expected to know it...
Any help would be greatly appreciated!
As a loud, low-frequency sound wave travels past a small balloon, the balloon's size is affected. Explain. (The effect is too small to be observed under ordinary circumstances).

You can feel a balloon vibrating to the bass notes in music.
sound is a longitudinal (or pressure) wave, the balloon is a sealed elastic container of pressurised air... what do you think happens when the air pressure outside the balloon changes?
