| Front | What is the unit for tensile stress? |
| Back | Pascal, which is equal to 1 Nm-2 |
| Front | How can we work out the critical angle? |
| Back | sinθc = n2 / n1 |
| Front | What is the effect of damping on resonance? |
| Back | Natural frequency remains the sameAs damping increases, amplitude of resonance decreases so peak of curve lowers, the resonance peak broadens and the resonance peak moves slightly to the left of the natural frequency when heavily damped |
