| amplitude | the height of any kind of wave |
| frequency | the number of times a wave vibrates in one second |
| refraction | the bending of waves as they travel from one medium (substance) to another |
| reflection | e change in direction of waves after they bounce off a surface |
| wavelength | the distance between a point on a wave and the same point on the next wave |
| visible spectrum | the band of energy on the electromatic spectrum that our eyes can detect |
| translucent | material that lets only some light pass through |
| transparent | material that lets almost all light pass through |
| concave | a surface that curves inward |
| convex | a surface that curves outward |
| decibel | a unit that is used to measure the loudness of a sound |
| electromatic spectrum | bands of wave energy that vibrate at different frequencies, some which we cannot see or hear |
