CONCEPT:

  • The electromagnetic wave is those wave which doesn't require any medium to propagate.
    • Electromagnetic waves are transverse in nature.

EXPLANATION:

  • A sound wave needs a medium to travel.
  • Light is an example of Electromagnetic waves. It doesn't need any medium to travel. Hence option 2 is correct.
  • Sound waves travel due to compression and rarefaction. 
  • Sound waves, water waves, and waves in a string are mechanical waves that require the medium to travel.

  • Electromagnetic waves are produced by an oscillating charged particle.
