CHAPTER 10 Transverse Wave – direction of the wave is perpendicular to the action creating it (ex. Light) Longitudinal Waves – wave is in the same direction as the motion of the objects causing the wave. They consist of compressions and separations (rarefactions). Period – the amount of time it takes a wave to complete one cycle. = T timetotal cycles Frequency – number of cycles that can occur in a given time period. = ( ) f total cyclestime in Hertz Hz Wavelength – length of one complete cycle ( , ) λ metres Amplitude – maximum disturbance of the wave from its zero point. = = f 1T T 1f Phase Shift – the relative position of the wave compared to a standard representation of it = = = v ∆d∆t λT λf = c λf Electromagnetic Spectrum Light is made up of oscillating electric and magnetic fields All waves travelling at the speed of light are included in the spectrum Each wave is distinguished by its wavelengths Rectilinear propagation of light – light travelling in a straight line
