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 |
