| Term | Definition |
|---|---|
| Wave | A wave is a disturbance that moves through matter or space. |
| Transverse waves | A transverse wave causes particles in matter to move back and forth at right angles to the direction in which the wave travels. |
| Congressional wave | A compressional wave causes particles in matter to move back and forth in the same direction in which the wave travels. |
| Wavelength | The distance between one point on a wave and the nearest point moving with the same speed and direction is the wavelength. |
| Frequency | The frequency of a wave is the number of wave lengths that pass by a point each second. |
| Law of reflecton | According to law of fraction the angles that the incoming wave make the normal equals the angle that the outgoing wave makes with the normal. |
| Refraction | Refraction is the change in direction of a wave when it changes speed as it travels from one material to another. |
| Diffraction | waves can change direction which is the bending of waves around an object. |
| opaque | allowing no light to pass through. |
| translucent | allowing light, but not detailed images, to pass through; semitransparent. |
| transparent | allowing light to pass through so that objects behind can be distinctly seen. |
| reflect | when light bounces off something |
| absorb | when light is going into something |
| transmit | when light goes through something |
| loudness | as it relates to sound |
| pitch | as it relates to sound |
