Chapter 7 & 8 7.1 – 7.3 Electromagnetic Radiation: Electromagnetic radiation can be described by equations that have the same mathematical form as equations that are used to describe waves. The mathematical description has two oscillating components (vectors) that are at right angles to o each other, and both of them are oriented 90 to the direction that the wave is travelling. The two components are called the electric vector and the magnetic vector (hence the name of the radiation). Like all wave phenomena, electromagnetic radiation has a wavelength, a frequency, and an amplitude. The wavelength and the frequency of the radiation are related to its speed and energy. The intensity of the radiation is propo
