Citation preview
The particle is propagate parallel to the direction of propagationThe particle is propagate perpendicular to the direction of propagationTransversewavePropagate by vibrationProduced by vibration or oscilationLongitudin-al waveTransfer energy Radio waveElectroma-gnetic waveWater waveSound Wave X-ray waveLight waveWave on strectched stringSound WaveType of waves
Wavefront
Wavefront is a line The direction of travel Join all the points of wave is always vibrating in phase perpendicular to the wavefront `
Oscillating System
An oscillation is a to and fro movement along a fixed path.Amplitude-maximun displacementPeriod time taken to complete one oscillation
