The behavior of EM radiation depends on its wavelength.]]> 2017-11-02 15:24:37 UTC https://padlet.com/304503/cblqquhlv2fv/wish/202958192 304503 https://padlet.com/304503/cblqquhlv2fv/wish/202959302 a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.]]> 2017-11-02 15:26:22 UTC https://padlet.com/304503/cblqquhlv2fv/wish/202959302 304503 https://padlet.com/304503/cblqquhlv2fv/wish/202960319 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 15:27:47 UTC https://padlet.com/304503/cblqquhlv2fv/wish/202960319 304503 https://padlet.com/304503/cblqquhlv2fv/wish/202961089 frequency definition. 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.]]> 2017-11-02 15:29:06 UTC https://padlet.com/304503/cblqquhlv2fv/wish/202961089 304503 https://padlet.com/304503/cblqquhlv2fv/wish/202963504 Physics One half the full extent of a vibration, oscillation, or wave. The amplitude of an ocean wave is the maximum height of the wave crest above the level of calm water, or the maximum depth of the wave trough below the level of calm water. The Amplitude of a pendulum swinging through an angle of 90° is 45°.]]> 2017-11-02 15:31:40 UTC https://padlet.com/304503/cblqquhlv2fv/wish/202963504 304503 https://padlet.com/304503/cblqquhlv2fv/wish/202964502 A wavelength is the distance between the crests of waves.
