Waves- Chapter 10
Mrs. Brandt's 8th grade Science
| Question | Answer |
|---|---|
| a wave strikes an object and bounces off | reflection |
| a repeating disturbance that transfers energy through matter or space | wave |
| ability of an object to vibrate by absorbing energy at its natural frequency | resonance |
| a wave that needs a medium to move through | mechanical wave |
| the bending of a wave caused by a change in speed at it moves from one medium into another and through another | refraction |
| a wave that moves up and down at right angles to the direction the wave travels | transverse wave |
| bending of a wave around a barrier | diffraction |
| wave that moves matter in a medium back and forth in the same direction the wave travels | compressional wave |
| material through which a wave moves and transfers energy | medium |
| a special type of wave pattern formed when waves of equal wavelength and amplitude travel in opposite directions continuously interferring with each other | standing waves |
| distance between one point in a wave and the nearest point just like it on the next wave | wavelength |
| two or more overlapping waves that have combined while moving through each other to form a new wave | interference |
| the measure of how many wavelengths pass a fixed point each second | frequency |
| the measure of how much energy a wave carries | amplitude |
