QuestionAnswer
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.
