| Question | Answer |
|---|---|
| what is the material through which mechanical waves travel | a medium |
| what is carried from particle to particle in a water wave | energy |
| what are the lowest points on a transverse wave | troughs |
| what determines the pitch of a sound wave | frequency |
| what is the distance between wave compressions | 1 Hz |
| what occurs when a wave strikes an object or surface and bounces off | reflection |
| what is the name for a change in the direction of a wave when it passes from one medium to another | diffraction |
| what type of wave is a sound wave | compressional |
| what color light has the shortest wavelength and largest frequency | blue |
| what do waves carry as they move | energy |
| what kind of wave does not need a medium through which to travel | light |
| what happens as a sound waves energy decreases | amplitude decreases |
| what unit is used to measure frequencies | hertz |
| what properties of a light wave determine its color | wavelength |
| when two waves overlap and interfere constructively, what does the resulting wave have | a greater amplitude |
| what happens when light travels from air into glass | it slows down |
| what behavior of light lets you see a sharp, clear image of yourself | reflection |
| why can't you see a clear image of yourself if the waters surface is rough | the light scatters in many different directions |
| matter moves at right angles to direction wave travels | transverse |
| matter moves in same direction as wave travels | compressional |
