IB Physics Deck For SCHS (Draft)
| Front | State one way in which a standing wave differs from a travelling wave. |
| Back | no energy propagated in a standing wave;the amplitude of a standing wave is not constant;points along a standing wave are either in phase or out of phase with each other |
| Front | Outline the features of an ideal step-down transformer. |
| Back | number of secondary coils < primary coils; coils wound around an iron core; ideally no flux leakage/zero resistive heating; |
| Front | What is the third law of thermodynamics? |
| Back | As temperature approaches absolute zero, the entropy of a system approaches a constant minimum. |
