Lecture 2 Notes, Electromagnetic Theory II
www.wtamu.edu- An electromagnetic wave with an arbitrary wave-shape can be thought of as a superposition of single-frequency plane waves. - If the dielectric material responds in the exact same way to plane waves of any frequency, then each component of the wave-shape will travel at the same speed, and the overall wave-shape will be preserved.

This means that although they appear to be very different, in fact they're all made of the same kind of vibrations - but at different . All electromagnetic waves travel at the same speed - 300,000,000 metres per second, which is the speed of light.

radiojove.gsfc.nasa.govWave #1 has 5 complete waves passing by in one second, while Wave #2 has 10 waves passing by in the same time. If you were to watch Wave #1 pass a point, the frequency would be 5 waves per second or 5 Hz. Wave #2 would have a frequency of 10 hertz. Wave #1 has half the frequency of Wave #2 and two times the wavelength.

gml.noaa.govThe electromagnetic (EM) spectrum is a name given to all of the different types of radiation. Electromagnetic radiation is energy that spreads out as it travels. Visible light radiation that comes from a lamp in someone’s house or radio wave radiation that comes from a radio station are two types of electromagnetic radiation. Other
