Reflection
|
When an object or a wave hits a surface through which it cannot pass, it bounces back.
|
|
|
Law of refraction
|
The rule that the angle of reflection equals the angle of incidence.
|
|
|
refraction
|
The bending of waves as they enter a new medium at an angle.
|
|
|
diffraction
|
The bending of waves as they move around a barrier or pass through an opening.
|
|
|
interference
|
The interaction between waves that meet.
|
|
|
constructive inference
|
The interference that occurs when waves combine to make a wave with a larger amplitude
|
|
|
deconstructive inference
|
The interference that occurs when two waves combine to make a wave with a smaller amplitude.
|
|
|
standing wave
|
A wave that appears to stand in one place, even though it is really two waves interfering as they pass through each other.
|
|
|
node
|
A point of zero amplitude on a standing wave.
|
|
|
antinode
|
A point of maximum amplitude on a standing wave.
|
|
|
resonance
|
resonance
The increase in the amplitude of a vibration that occurs when external vibrations match an object’s natural frequency. |
