| Question | Answer |

| wave | a disturbance that transfers energy from one place to another without transferring matter |
| mechanical wave | a wave that travels only though matter |
| medium | a material in which a wave travels |
| transverse | a wave in which a disturbance is perpendicular to the direction the wave travels |
| longitudinal wave | a wave vibration in the direction of propagation. |
| sound wave | a wave of compression and rarefaction by which sound is propagated in an elastic medium such as air |
| amplitude | the maximum extent of a vibration or oscillation measured from the positions of equilibrium |
| wave length | the spatial distance between two consecutive identical point in wave cycle |
| pitch | the quality of sound governed by the rate of vibrations producing it the degree of highness or lowness of tone |
