Transverse Wave | Particles move perpendicularly to the direction the waves travels |
Mechanical Wave | Waves that require a medium |
Electromagnetic Wave | Are a disturbance in electric and magnetic fields |
Amplitude | Is a measure of how far particles in the medium move away from their normal resting place |
Wavelength | The distance over which the wave shape repeats |
Wave Period | Is the time required for one cycle |
Frequency | Tells you how many cycles occur in an amount of time most commonly |
Hertz | Unit of measure for frequency |
Wavefronts | The peaks can be drawn as shapes such as circles or spheres |
Wave Speed | The speed at which a wave travels, depends on the properties of the medium |
