Waves & Light
Term | Definition |
---|---|
Medium | The material through which a wave travels. |
Wave | A disturbance that transfers energy from one place to another. |
Longitudinal wave | Particles move and forth in the same direction that the wave travels, or parallel to the wave. |
Transverse wave | When particles perpendicularly to the direction the wave travels. |
Mechanical wave | A wave that requires a medium through which to travel. |
Electromagnetic wave | A disturbance in electric and magnetic fields. |
Amplitude | A measure of how far the particles in the medium move away from their normal rest position. |

Wavelength | The distance from any point on a wave to identical point on the next wave. |
Wave period | The time required for one cycle. |
Frequency | A wave tells how many cycles occur in an amount usually 1 s. |
Hertz | One hertz is equal to one cycle per second. |
Wave speed | The speed at which a wave travels |
