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 |
