Questions and Answers List
level questions: waves
| Question | Answer |
|---|---|
| NA | NA |
| what are transverse waves | vibrations that occur perpendicular to the direction in which the wave is travelling |
| what are longitudinal waves | vibrations that occur parralel to the direction in which the wave is travelling |
| examples of tranverse waves | UV, light, water, x rays |
| examples of longitudinal waves | sound waves |
| what are longitudinal waves made up of | compressions and rarefractions |
| how do you find wave speed | wave speed (m/s) = frequence (HZ) x wavelength (m) |
| how do you find frequency | 1 / time period |
| what is refraction | where a wave changes direction when it enters a new medium due to a change in its speed |
| how do water waves in deep water travel | travel fast, widely spread |
| how do water waves in shallow water travel | travel slow, closer together |
| what is defraction | wave spread out when they pass through a gap |
| what happens when the wave passes through the gap | gap size = wavelength |
| what happens when the wave passes through the gap | wider gaps = less diffraction |
