| Question | Answer |
| Waves | A traveling disturbance consisting of coordinated vibrations that transmit energy with no net movement of matter. |
| Transverse wave | A wave in which the oscillations are perpendicular to the direction the wave travels. |
| What are the examples of transverse waves? | Waves on a rope, electromagnetic waves, some seismic waves. |
| Longitudinal wave | A wave in which the oscillations are along the direction the wave travels. |
| What are some examples of longitudinal waves? | Sound in the air, some seismic waves. |
| Amplitude | The maximum displacement of points on a wave, measured from the equilibrium position. |
| Wavelength | The distance between two successive "like" points on a wave, for example, the distance between two adjacent peaks or two adjacent valleys. |
| Frequency | The number of cycles of a wave passing a point per unit time. the number of oscillations per second in the wave. |
| Transmission | Light passing through material such as polaroid filters. |
| Reflection | Light bouncing of a surface. |
| Refraction | Light traveling through a material. |
| Scattering | When light strikes the atoms. |
| Doppler effect | The apparent change in the frequency of wave fronts emitted by a moving source, example is a train traveling along a track blowing a whistle. |
| Echolocation | Is the process of using the waves reflected from an object to determine its location. |
| What are some examples of echolocation? | Radar and sonar. |
| Interference | Arises when two continuous waves, usually with the same amplitude and frequency, arrive at the same place. |
| Pure tone | Is a sound with a sinusoidal waveform. |
| Complex tone | Is a complex sound wave. The waveform of a complex tone repeats itself but is not sinusoidal. |
| Loudness | Is determined mainly by the amplitude of the sound wave. The greater the amplitude of the sound wave that reaches your eardrums, the greater the perceived loudness of the sound. |
| Pitch | A sound is the perception of highness or lowness. The sound of a soprano voice has a high pitch and that of a bass voice has a low pitch. The pitch of a sound depends primarily on the frequency of the sound wave. |
