Unformatted text preview: Scientifc Notation milli , written m , means 10-3 . So 1/1000 oF a meter is a millimeter, or 1mm micro , written , means 10-6 . So the wavelength oF light is 0.5 micrometers = 0.5m mega , written M , means 10 6 . So a 100 MHz M station is generating waves at 10 8 Hz nano , written n , means 10-9 . So the wavelength oF yellow light is 500 nanometers = 500 nm 650nm 500nm 400nm 0.65m 0.5m 0.4m Waves - the Electromagnetic Spectrum Waves can be either Periodic or Aperiodic ! Periodic wave Aperiodic wave ! Periodic wave space Wavelength For periodic waves, we can identify a wave length , ! , by measuring the distance between unique points ! Periodic wave ! Periodic wave space Period and Frequency For periodic waves, we can identify a period , T, by measuring the time taken for a wavelength ! to pass a given point - The frequency , ! , is the inverse of the period i.e. ! = 1/ " and is the number of times per second that an oscillation occurs at any xed point in space Wavelength, Frequency, and Velocity For periodic waves, we can identify a speed , v, by speed = distance/time speed = Wavelength/Period speed = Wavelength x frequency v = #! Wavelength, Frequency, and Velocity For periodic waves, we can identify a speed , v, by Speed = distance/time Speed = Wavelength/Period Speed = Wavelength x frequency v = #!...
