| Question | Answer |
| What is meant by the term amplitude? | "How High" the wave is from the equilibrium. |
| What is meant by the term wavelength? | The distance between two corresponding points on a wave. or (Distance of one oscillation) |
| What is meant by the term frequency? | How many waves pass by every second |
| Describe a transverse wave. | Particles oscillate perpendicular to the direction of energy transfer |
| Describe longitudinal waves. | Particles oscillate along the direction of the energy transfer. |
| What is meant by the term, in-phase? | Two points that are exactly one oscillation or a multiply of one oscillation apart. |
| What is meant by the term, out-of-phase? | Two points that reach the opposite extremes of the oscillation at the same time. |
| What is one wavelength in terms of π? | 2π |
| What is meant by superposition? | When two or more waves combine. |
| What is constructive interference? | When two waves in-phase combine |
| What is destructive interference? | When two waves out-of-phase combine. |
| How are stationary waves formed? | When two waves of the same frequency travel in the opposite direction. |
| What are anti-nodes? | Points on a wave that have the maximum displacement. |
| What are nodes? | Points on a wave that have the least amount of displacement. |
| What wave type has fixed nodes and no energy is transferred? | Stationary Waves. |
| What are progressive waves? | Waves that have crests that move at the speed of the wave and transfer energy. |
| What is a fundamental vibration? | The fundamental vibrational mode of a stretched string is half the wavelength |
| What are overtones? | integer multiples of the fundamental frequency. |
