Mechanical Wave Vs Electromagnetic Wave Form 4 Physics

This is something new in the Form 4 KSSM new syllabus. The text book did made clear comparison and we believe this may be really important for Paper 1 question.

Mechanical Wave

  • Need medium to transfer energy
  • Does not transfer matter
  • Vibrating medium particles
  • Sound wave, seismic waves

Electromagnetic Wave

  • Do not need medium to propagate its energy
  • Oscillating of electric and magnetic field
  • Examples: Light wave, microwave, radio waves
