What are waves?
a disturbance that transfers energy from one place to another.
what is a wave?
a type of wave that moves the medium parallel to the wave.
what is a longitudinal wave?
the maximum distance the particles carrying away the wave move away from the resting position.
what is amplitude?
When an object hits a surface through which it cannot pass.
what is reflection?
the interaction between two waves
what is interference?
waves that need a medium to travel through.
the material through which the wave travels.
what is a medium?
The distance between two corresponding parts of the wave.
what is wavelength?
the angle of incidence is always equal to the angel of reflection.
what is the law of reflection?
When waves combine to make a wave with a larger amplitude.
what is constructive interference?
waves that do not need a medium to travel through.
what are electromagnetic waves?
the high point of a transverse wave.
what is a crest?
the number of waves per second.
what is frequency?
When a wave enters a new medium, its speed changes.
what is refraction?
When two waves combine to make a wave with a smaller amplitude.
what is destructive interference?
a repeated up-and-down back-and-forth movement that causes a wave.
what is a vibration?
the low point of the transverse wave.
what is a trough?
the measurement of frequency.
What are hertz?
the wave bends.
what happens to the wave in refraction?
If the incoming wave and a reflected wave have just the right frequency, they produce a combined wave that appears to be standing still.
what is a standing wave?
a type of wave that moves the medium across, in right angles to the wave.
what is a transverse wave?
the spread out part of the coil.
the close together parts of the coil.
what are rarefactions?
what are compressions?
wavelength x frequency.
what is speed?
When a wave moves around a barrier or through an opening in a barrier, it bends and spreads out.
what is diffraction?
an increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
what is resonance?
