# B.4. Forced Vibrations and Resonance (HL)

Resonance is a fascinating phenomenon in Physics. It is the reason we have string and wind instruments, yet also part of the reason earthquakes can be so damaging. It is even part of the reason why you are likely to spill some of your cup of tea when walking. The latter was the recipient of an Ig Nobel award in Fluid Dynamics back in 2012 (a set of awards on genuine scientific - if a little odd-  research that makes you laugh, then think...).
