Term | Definition |
---|---|
Wave | A traveling disturbance that carries energy from one place to another |
Mechanical waves are created when a source of energy causes a medium to | move |
Speed = | wavelength multiplied by frequency |
Refraction | The bending of waves due to a change in speed |
Diffraction | The bending of waves around an obstacle |
Interference | The interaction between two waves that meet |
Constructive Interference | When waves combine to make a wave with larger amplitude |
Standing wave | When an incoming wave combines with a reflected wave in such a way that the combined wave appear to be standing still |
Resonant Frequency | When vibration travels through an object at the same speed of the object it travels through |
the energy passes from one particle to another | A wave travels through a medium because |
How they move | A mechanical wave is classified according to |
Hertz | Frequency is measured in |
Reflection | When a wave hits a surface and bounces off of that surface |
Destructive Interference | When waves combine to produce a smaller or zero- amplitude wave |
Light travels faster then sound | The reason for why you see lightning before hearing thunder |
Longitudinal Wave | Compression and rarefaction are characteristics of a |
Wavelength | The distance between two consecutive crests |
Transverse Wave | Where the motion of the medium of the wave is traveling at a right angle to the motion of the wave |
Frequency | Waves / Seconds |
Compression | Space where the particles are crowded together |
Rarefaction | Space between compression |
