Wave Interactions

TermDefinition
Reflection the bouncing back of a wave when it hits a surface through which it cannot pass
Law of Reflection the rule that states that the angle of reflection equals the angle of incidence
Refraction the bending of waves as they enter a new medium causing a change in the speed of the waves
Diffraction the bending and spreading of waves as they move around a barrier or pass through an opening
Transparent transmitting light without interruption or scattering so as to be seen through clearly
Translucent transmitting light with scattering and diffusion so as to be blurry or semitransparent
Opaque allowing no transmission of light energy so as to be impenetrable to sight
Absorption the taking up and storing of energy, such as light or sound, without it being reflected or transmitted
Interference the interaction between two or more waves that meet or intersect
Constructive Interference the interference that occurs when waves combine to make a wave with a larger amplitude
Destructive Interference the interference that occurs when waves combine to make a wave with a smaller amplitude or to cancel the wave
Standing Waves a wave that appears to stand in one place, even though it is really two waves traveling in opposite directions interfering as they pass through each other
Resonance the increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency
