Unformatted text preview: and energy. main parameters of the wave nature 2. It is electromagnetic radiation, composed of fluctuating electric and magnetic fields that are perpendicular to the motion of the wave and to each other. 3. It can also be described as a particle, with characteristics of mass and momentum. 7 Light as a type of electromagnetic radiation All types of electromagnetic radiation move through a vacuum at the speed of light (c), a constant. The speed of light is equal to the product of the wavelength (λ) and frequency (v). That is: Where λ v c c=λv = Wavelength, in units of metres (m) frequency = ___________________, in units of s-1 (or hertz, Hz) = velocity of light (3.00 x 108 m s-1 in a vacuum) From this relationship we can see that the frequency is inversely related to the wavelength. 8 4 05-Sep-13 Consider two beams of the same yellow light. Imagine that one beam has its wavelength doubled; the other has its frequency doubled. Which of these two beams is then in the ultraviolet region? frequency- large no.s, wavelength- very small in nm answer- frequency: if u double it, u move in the UV regime 9 Example: A dental hygienist uses x-rays* to take a series of dental radio...
