The behavior of EM radiation depends on its wavelength.]]> 2017-11-02 15:27:21 UTC https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960024 3097213 https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960210 Do not conclude that sound is a transverse wave that has crests and troughs. Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner.]]> 2017-11-02 15:27:35 UTC https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960210 3097213 https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960377 Wave speed is the speed at which a wave travels.Wave speed is related to wavelength, frequency, and period by the equation wave speed = frequency x wavelength. The most commonly used wave speed is the speed of visible light, an electromagnetic wave.]]> 2017-11-02 15:27:53 UTC https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960377 3097213 https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960539 In physics, the number of crests of a wave that move past a given point in a given unit of time. The most common unit of frequency is the hertz (Hz), corresponding to one crest per second. The frequency of a wave can be calculated by dividing the speed of the wave by the wave length]]> 2017-11-02 15:28:11 UTC https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960539 3097213 https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960683 in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.]]> 2017-11-02 15:28:25 UTC https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960683 3097213 https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960884 the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave's shape repeats, and thus the inverse of the spatial frequency.]]> 2017-11-02 15:28:43 UTC https://padlet.com/3097213/3pc5bz7gt3mm/wish/202960884 3097213 https://padlet.com/3097213/3pc5bz7gt3mm/wish/202961031 In physics, any regularly recurring event, such as surf coming in toward a beach, that can be thought of as a disturbance moving through a medium. Waves are characterized by wavelength, frequency, and the speed at which they move.]]> 2017-11-02 15:28:59 UTC https://padlet.com/3097213/3pc5bz7gt3mm/wish/202961031
