Waves/Sound
| Question | Answer |
|---|---|
| Wave | A disturbance that carries energy through matter or space without transferring the matter. |
| Transverse Wave | A mechanical wave in which the movement of the particles are parallel to the motion of the energy. |
| Trough | The bottom part of a wave. |
| Medium | A material through which a wave travels (liquid, solid, and gas) |
| Energy | The ability to do work |
| Frequency | The number of waves that pass a point in a given period of time. |
| Wavelength | The length between crest to crest or trough to trough. |
| Mechanical Wave | When a source of energy causes a medium to vibrate. |
| Longitudinal Wave | A mechanical wave in which the movement of the particles are parallel to the motion of the energy. |
| Compression | The particles are close together. |
| Vibrations | The rapid motion of the particles of the elastic body or substances back and forth |
| Amplitude | The distance the medium vibrates from the rest position. |
| Example of transverse wave | light and electromagnetic waves |
| example of longitudinal wave | sound wave or ultrasound wave |
| Relationship between wavelength, frequency, and pitch | The more frequency the shorter the wave length and higher pitch. |
| Relationship between amplitude and volume | The higher the amplitude the louder the volume is, However high or low the amplitude is, is how high or low the volume will be |
| How does frequency change light and sound? | The frequency changes the sound because the more frequency the higher the pitch. The higher the frequency goes closer to the color blue and the less frequency, the color red. |
| Explain the relationship between amplitude and the brightness of light? | However high or low the amplitude is, is how high or low the brightness of the light is going to be. |
| Explain why certain objects produce higher pitches and other objects produce lower pitches. | Objects produce different pitches because the bigger the instrument the lower the pitch, like the different sized drums. The bigger the animal the lower the pitch. An elephant has a lower pitch than a dog does. |
| What impacts the size of the ocean waves? Why are there such huge waves off the coast of Hawaii and Northern Californina? | Wind impacts the size of waves because the stronger the wind, the bigger the waves. Strong winds and open ocean affects the size of wind off the coast of Hawaii and Northern California. |
| When particles are far apart | rarefaction |
