Waves in communication

1. Progressive Waves

   • Wave motion
     • Oscillation
       • A regularly repeating motion to a central value
     • Frequency
       • The number of whole cycles occuring in one second
     • Period
       • The time taken for one whole oscillation to take place
     • Amplitude
       • MAximum value of displacement in oscillation cycle
     • Wavelength
       • Distance between two adjacent wavefronts
   • Wave speed
     • Wave speed = Wavelength * Frequency
   • TRANSVERSE WAVES
     • Wave motion is perpendicular to wave direction
     • Examples of transvers waves are: em waves, mexican wave
   • LONGITUDINAL WAVES
     • Examples of longitudinal waves are: sound waves
