Question | Answer |
---|---|
What determines the speed of a wave? | the medium it is traveling through. |
When objects vibrate at their natural frequency, it is called | Resonance |
In a wave, the medium and wave are in the same direction; in a wave, the medium and wave are at right angles. | compressional, and transverse wave |
What happens when a wave when it changes mediums? | The frequency of the wave remains the same, but the speed doesn't. |
Amplitude indicates how much ___ a wave has. | energy |
What allows you to see objects? | reflection of light |
What kinds of waves can be reflected? | All kinds |
Where does light travel fastest? | through space |
Where does sound travel fastest? | solids |
How do you make a sound wave travel faster? | increase the temperature of the medium. |
When you squeeze the coils of a spring and release them, you create a | Compressional wave |
Standing waves are created by two waves that are equal in _________________________ and _______________________________, but opposite in ___________________________________. | wavelength and amplitude, directions |
If you decrease the frequency of a wave, what happens to the wavelength? | Increases |
If you increase the frequency of a wave, what happens to the wavelength? | Decreases |
How you can you tell a high amplitude compressional wave from a low amplitude compressional wave? | Higher amplitude waves have tighter or more dense compressions and looser, less dense rarefactions than low amplitude waves. |
