wave interference's
| Question | Answer |
|---|---|
| diffraction | the spreading of waves around obstacles |
| refraction | the change in direction of a wave passing from one medium to another |
| standing wave | occurs when two waves of the same frequency and amplitude are moving in opposite directions and interfere with each other |
| reflection | when light bounces off an object |
| constructive interference | happens when two waves overlap in such a way that they combine to create a larger wave |
| destructive interference | occurs when waves come together so that they completely cancel each other out |
| principle of superposition | when two or more waves overlap in space, the resulting disturbance is equal to the algebraic sum of the individual disturbances |
| beats | when two waves of nearby frequencies overlap and create a new resultant wave |
| interference | the superposition of waves, causing an increase or decrease in the amplitude of the resulting wave |
| nodes | a point along a standing wave where the wave has minimum amplitude |
| sound | A vibration that propagates as an audible wave of pressure, through a medium such as a gas, liquid or solid |
| pitch | How high or low a sound seems to a listener |
| infrasonic | sound waves with a frequency below the lower limit of human audibility. |
| ultrasonic | mechanical waves produced at very high frequencies above human hearing |
| doppler | the change in the frequency or, equivalently, the period of a wave |
| acoustics | the science that deals with the production, control, transmission, reception, and effects of sound |
