| Question | Answer |
|---|---|
| compressional waves | a wave in which matter vibrates in the same direction as the energy waves traveling through it is called a ---- ---- |
| intensity | a measure of the amount of energy in a wave |
| music | pleasant sound with regular wave pattern |
| noise | sound with no regular wave pattern |
| photon | a bundle of energy that is released when an atom loses some energy |
| wavelength | the distance between a point on one wave and the same point on the next wave |
| frequency | refers to the number of waves that pass a point in a given amount of time |
| amplitude | the distance between a wave's midpoint and its crest or trough |
| electromagnetic | all waves that radiate from the sun are ---- waves |
| primary | red, green, and blue are the ---- colors of light |
| cones | are light sensitive cells in your eyes |
| opaque | are objects that light does not pass through |
| rocks | sensors in your eye that are not sensitive to color, but can respond to smaller amounts of light are rocks |
| transparent | a ---- object allows light to pass though it |
| wavelength | a stained glass window is a substance that transmits different ---- of light |
| what is color | visible light is a tiny part of the electromagnetic spectrum of energies given off by the sun |
| energy | photons from the sun travel through space carrying different amounts of --- |
| radiate | all waves that ---- from the sun are called electromagnetic waves |
| electromagnetic | the entire range of energy waves is called the ---- spectrum |
| primary colors | ---- ---- are red, blue, and green by sensing only these three colors, people see a wide range of colors |
| why do we see color | the human eye contains 3 different types of cones, each of which responds to a different primary color |
| black | when none of the cones are stimulated by light, we see ----- |
| opaque | does not allow light to pass through |
| transparent | allows light to pass through so that objects on the other side can be seen |
| echo | a refected soun wve |
| states of matter | solid, liquid, gas |
| primary colors | blue, green and red |
| light | is a form of energ that mves out from a central point |
| How is sound produced? | when matter vibrates |
| pitch | how high or low sound is |
| low pitch | further apart |
| crest | high point on a wave |
| trough | low point on a wave |
| why do we see color? | cones in your eyes red, blue, green, when we see black all colors when we see white |
