Studied by 2 peopleDiffraction
________: occurs when an object causes a wave to change direction and bend around it.
Resonance
________: The process by which an object is made to vibrate by absorbing energy at its natural frequencies.
Light waves
________ have a much shorter wavelength.
Rarefaction
________: less- dense region of a compressional wave.
Refraction
________: he bending of a wave caused by a change in its speed as it moves from one medium to another.
Interference
________: When two or more waves overlap and combine to form a new wave.
Period
________: the amount of time it takes one wavelength to pass a point.
Amplitude
________: related to the energy carried by a wave.
Frequency
________ is expressed in hertz (Hz)
destructive interference
In ________, the waves subtract from each other as they overlap.
seismic waves
When objects on Earths surface absorb some of the energy carried by ________, they move and shake.
Sound waves
________ usually travel faster in liquids and solids than they do in gases.
obstacle
If the ________ is much larger than the wavelength, almost no diffraction occurs.
Light waves
________ travel slower in water than in air.
Sound waves
________ travel through the air to reach your ears.
Frequency
________: the number of wavelengths that pass a fixed point each second.
Diffraction
________ and refraction both cause waves to bend.
Wave
________: a repeating disturbance or movement that transfers energy through matter or space.
Medium
the matter the waves travel through
Transverse Wave
matter in the medium moves back and forth at right angles to the direction that the wave travels
Compressional Wave
matter in the medium moves back and forth along the same direction that the wave travels
Crests
high points of a wave
Troughs
low points of a wave
Rarefaction
less-dense region of a compressional wave
Wavelength
the distance between one point on a wave and the nearest point just like it
Period
the amount of time it takes one wavelength to pass a point
Amplitude
related to the energy carried by a wave
Refraction
he bending of a wave caused by a change in its speed as it moves from one medium to another
Diffraction
occurs when an object causes a wave to change direction and bend around it
Interference
When two or more waves overlap and combine to form a new wave
Standing Wave
special type of wave pattern that forms when waves equal in wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other
Resonance
The process by which an object is made to vibrate by absorbing energy at its natural frequencies
