Wave
Question | Answer |
---|---|
A disturbance that transfers energy from place to place | Wave |
Mechanical waves are created when a source of energy causes a medium to | Move |
The speed of a wave is its wavelength times its | Frequency |
The bending of waves due to change in speed | Refraction |
Bending of waves around the edge of a barrier | Diffraction |
Interaction between two waves that meet | Interference |
Waves combine to make a wave with a larger amplitude | Constructive |
When a incoming wave combines with a reflected wave in a way that the combines wave appears to be standing still. | Standing Wave |
Occurs when vibrations traveling threw an object match the objects natural frequency. | Resonance |
A wave travels threw a medium because | Energy passes from particle to particle |
Mechanical waves are classified according to | how they move |
Frequency is measured in units called | Hertz / Hz |
When a wave hits a object that it can not pass and bounces back | Reflection |
Waves combine to produce a smaller amplitude wave | Destructive Interference |
Why do you see lightning before Thunder | Light travels faster then sound |
Compression and Refractions are characteristic to | Longitudinal wave |
