Questions & Step-by-Step Solutions

Which of the following waves requires a medium to propagate?
Correct Answer: Sound waves
  • Step 1: Understand what a wave is. A wave is a disturbance that travels through space and matter.
  • Step 2: Learn about the two main types of waves: mechanical waves and electromagnetic waves.
  • Step 3: Know that mechanical waves, like sound waves, need a medium (like air, water, or solid materials) to travel through.
  • Step 4: Recognize that electromagnetic waves, like light, do not need a medium and can travel through empty space (a vacuum).
  • Step 5: Conclude that sound waves are the type of wave that requires a medium to propagate.
