The distance crest to crest or compression to compression, trough, amplitude, frequence, wavelength, The highest part of a transverse wave, crest, trough, frequency, wavelength, The lowest part of a transverse wave, crest, frequency, trough, amplitude, The amount of energy a wave has (or the distance from the wave at rest to its highest point), frequency, crest, trough, amplitude, What is not an example of a transverse wave?, an ocean wave, birds chirping, The energy in a transverse wave moves , forward from the source and spreads out, perpendicular to the medium, in a straight line, The energy in a longitudinal wave moves, perpendicular to the medium, forward from the source and spreads out, in a straight line, Waves travel fastest in solids because their molecules are close together, false, true, If it is hot outside the sound waves (longitudinal waves) passing through the air will, slow down, speed up, The number of waves that pass a stationary point in one second, amplitude, wavelength, frequency, If it is cold outside, the longitudinal waves (sound waves) will travel , slower, faster, Which is not a longitudinal wave?, dogs barking, people singing, ocean waves, bells ringing, The transfer of energy from one place to another is called a wave., false, true, Transverse and longitudinal waves both have, troughs, amplitude, compressions, crests, Transverse and longitudinal waves need a medium to transfer energy from one place to another., false, true, Longitudinal and transverse waves are NOT mechanical waves., True, False, The bunched coils in a longitudinal wave are called the wave's , crests, compressions, rarefactions, troughs, The unit that represents the frequency of a wave is, m/sec, Hz (Hertz), meters, There isn't a unit for this, Transverse and longitudinal waves both have, compressions, wavelengths and amplitudes, troughs, rarefactions, You would know if a storm is coming close to shore by the ___________________ of the waves., frequency of the waves, compressions , rarefactions, If a wave has a short wavelength, it will have a low frequency., False, True, The wave property that allows us hear our voice., diffraction, reflection, refraction, The wave property that lets us hear people talking in the hallway when we are in the classroom., diffraction, refraction, reflection, This is an example of which wave property?, reflection, diffraction, refraction, When a wave passes through an opening and spreads out on the other side it is called, refraction, reflecion, diffraction, When a wave bounces off a surface it is called, reflection, refraction, diffraction, When a wave changes its speed because it has gone from a gas to a liquid, it is called, reflection, refraction, diffraction, A wave with a long wavelength will have a low frequency. 75 Hz, True, False, Interference is when 2 or more waves combine., True, False, Destructive interference is when waves combine and cancel out their amplitudes and then the energy moves on., True, False, An example of constructive interference of longitudinal waves is, at lunchtime in the commons, When everyone sings Happy Birthday together, Constructive interference of waves happens and the amplitude gets higher when the waves meet., True, False.
