SCIANCE
question | answer |
---|---|
A wave travels faster in a more _______ medium | elastic |
A wave travels slower in a more ______ medium | dense |
The bouncing back of a wave from a boundary that does not absorb all of its energy | reflection |
The bending of waves due to a change in speed. | refraction |
the bending of waves around an obstacle | diffraction |
when the crest of one wave meets the crest of another wave, the amplitude of the single wave produced is equal to the sum of the two original amplitudes | Constructive inerference |
When the crest of one wave meets the trough of another wave, the amplitudes are subtracted and a smaller disturbance is produced | destructive interference |
A wave that does not appear to be moving | Standing wave |
A ___ is a traveling disturbance that carries energy from one place to another | wave |
A ___ is a repeated disturbance that creates waves | vibration |
A ___ is a substance through which waves can travel. All phases of matter ( solid, liquid, gas ) can act as a medium | medium |
Waves that require a medium are ___ waves | mechanical |
the greatest movement from the resting position. Also known as height. Measures how much energy a wave has | amplitude |
the distance from crest - to - crest or trough - to - trough | wave length |
the number of complete wave cycles that pass a certain point per unit time | frequency |
a wave in which the motion of the medium is at a right angle to the motion of the wave | transverse wave |
the motion of the medium is in the same direction as the motion of the wave. An example is sound waves | longitudinal wave |
