WEEK 3-4: waves

OBJECTIVES (CONCEPTS & SKILLS:) :  

 Wave motion ,transverse and longitudinal waves.

  Displacement relation in a progressive wave.

  Speed of travelling wave, reflection of waves.

  Superposition of waves- stationary waves , beats.

  Doppler effect.                                                                                                                                                                                                                          The teacher will keep the following skills in view:
