| Question | Answer |
|---|---|
| a disturbance that transmits energy through matter or space | wave |
| the matter through which a wave travels | medium |
| a wave that requires a medium | mechanical wave |
| a wave that is a disturbance in electric and megnetic fields, does NOT require a medium. Also called a light wave. | electromagnetic wave |
| a wave that couses the particles of a medium to vibrate perpendicularly to the direction the wave travels | transverse wave |
| a wave that causes the particles of the medium to vibrate parallel to the direction the wave travels. | longitudinal wave |
| particles move in circles in fluids | surface waves |
| the highest point of a transverse wave | crest |
| the lowest point of a transverse wave | trough |
| the maximum distance that a wave travels from its normal position | amplitude |
| the distance between any two successive identical parts of a wave( distance between crests) | wavelength |
| the number of vibrations that occur in a 1 second time interval, measured in Hertz. | frequency |
| the apparent change in frequency of a wave when the source or the observer is moving. | Doppler effect |
| the bouncing back of a wave as it meets a surface or boundary. | reflection |
| the bending of a wave as it passes an edge or an opening. | diffraction |
| the bending of waves as they pass from one medium to another | refraction |
| the combination of two or more waves that exist in the same place at the same time. | interference |
| when two waves combine and the resulting wave is larger than the originals | constructive interference |
| when two waves combine and the resulting wave is less than the originals. | destructive interference |
| a wave that interferes with itself and appears not to be moving along the medium. Nodes and antinodes are produced | standing wave |
| region of a standing wave that appears to not vibrate | node |
| region of a standing wave that has the most vibration | antinodes |
