Electromagnetic waves are transverse waves, since the electric and magnetic fields oscillate at a right angle to the direction of motion. 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144365032 2016-12-19 18:22:54 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144365032 LONGITUDINAL WAVES 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144365450 Mechanical longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium.]]> 2016-12-19 18:24:57 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144365450 WAVELENGTHLight is measured by its wavelength, one wavelength equals the distance between two successive wave crests or troughs. 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144365784 2016-12-19 18:26:20 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144365784 Frequency 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144366139 In physics, Frequency is 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).]]> 2016-12-19 18:27:52 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144366139 RADIO WAVESRadio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144366545 2016-12-19 18:29:29 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144366545 MICROWAVESelectromagnetic wave with a frequency in the range of 100 megahertz to 30 gigahertz (lower than infrared but higher than other radio waves). 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144366688 2016-12-19 18:30:03 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144366688 INFRAREDinterference is the process in which two or more light, sound, or electromagnetic waves of the same frequency combine to reinforce or cancel each other, the amplitude of the resulting wave being equal to the sum of the amplitudes of the combining waves. 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144366773 2016-12-19 18:30:26 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144366773 Visible Light Visible light is a form of electromagnetic radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144367031 2016-12-19 18:31:45 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144367031 ULTRAVIOLETUltraviolet light is a form of radiation which is not visible to the human eye. It's in an invisible part of the electromagnetic spectrum. Radiated energy, or radiation, is given off by many objects. 12237318 https://padlet.com/12237318/mzf8dns5l4r/wish/144367101 2016-12-19 18:32:02 UTC https://padlet.com/12237318/mzf8dns5l4r/wish/144367101 X-Rays A relatively high-energy photon with wavelength in the approximate range from 0.01 to 10 nanometers.
