  • Waves- Chapter 14 (2)
    • Phase difference: Amount by which one oscillation leads or lags behind another. ( Measured in degrees).
    • Wave energy: Particles in a wave never move along! They only oscillate at a fixed point. Each particle vibrates as it does pushes its neighbour transferring energy to it.
    • INTENSITY: POWER/ CROSS SECTIONAL AREA
    • Frequency of  a sound wave can be measured using a cathode ray oscilloscope.
    • Polarisation
      • Only transverse waves can be polarised
      • A plane polarised wave has oscillations in only one plane.
    • Wave speed= f*w=w/T
