| A | B |
|---|
| RESONANCE | VIBRATIONS TRAVELING THROUGH AN OBJECT MATCH THE OBJECT'S NATURAL FREQUENCY |
| ANTINODES | INTERFERENCE THAT RESULTS IN MAXIMUM ENERGY PRODUCED |
| DESTRUCTIVE INTERFERENCE | CAUSE A DIFFERENCE IN AMPLITUDE AS A RESULT OF THE WAVES CANCELING THE EFFECT |
| CONSTRUCTIVE INTERFERENCE | WAVES COMBINE CAUSING AMPLITUDE TO INCREASE |
| INTERFERENCE | TWO OR MORE WAVES MEET AND HAVE AND CAUSE AN EFFECT ON EACHOTHER |
| DIFFRACTION | BENDING OF WAVE AROUND A BARRIER |
| REFRACTION | WAVES CHANGING FROM ONE MEDIUM TO ANOTHER CAUSING THE SPEED OF THE WAVE TO CHANGE |
| ANGLE OF REFLECTION | the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface. |
| ANGLE OF INCIDENCE | The angle formed by a ray or wave incident on a surface and a line perpendicular to the surface at the point |
| REFLECTION | A WAVE BOUNCING OFF OF A SURFACE THE WAVE CANNOT PASS THROUGH |
| NODE | point at which a wave has an amplitude of zero |
| HERTZ | derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second |
| DECIBELS | unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds |
| WAVELENGTH | the distance between successive crests of a wave, |
| TROUGH | the minimum or lowest point in a cycle. |
| CREST | point on a wave with the maximum value of upward displacement within a cycle |
| RAREFACTION | COILS OF LONGITUDINAL WAVE ARE SPREAD APART |
| COMPRESSION | COILS OF LONGITUDINAL WAVE ARE CLOSE TOGETHER |
| AMPLITUDE | MAXIMUM DISTANCE THE PARTICLES OF A WAVE ARE MOVED FROM REST POSITION |
| SURFACE | TYPE OF WAVE THAT IS COMBINATION OF TRANSVERSE AND LONGITUDINAL OCCURRING AT BOUNDARY OF TWO DIFFERENT MEDIUMS |
| LONGITUDINAL | PARTICLES MOVE PARALLEL IN COMPRESSIONS AND RAREFACTIONS |
| TRANSVERSE | WAVES MOVE AT UP AND DOWN COMPARED TO THE MEDIUM |
| MECHANICAL WAVE | TYPE OF WAVE THAT REQUIRES A MEDIUM |
| VIBRATION | A REPEATED BACK AND FORTH OR UP AND DOWN MOTION THAT IS THE SOURCE OF A WAVE |
| MEDIUM | MATERIAL A WAVE TRAVELS THROUGH |
| WAVE | DISTURBANCE THAT TRANSFERS ENERGY FROM PLACE TO PLACE CREATED WHEN A SOURCE OF ENERGY CAUSES A MEDIUM TO VIBRATE |
