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 |
