Questions & Step-by-Step Solutions

What is the principle of superposition in wave theory?
  • Step 1: Understand that waves can be sound waves, light waves, or water waves.
  • Step 2: Know that when two or more waves meet in the same place, they overlap.
  • Step 3: The principle of superposition says that when these waves overlap, they combine together.
  • Step 4: To find the new wave (resultant wave), you add the heights of the individual waves at each point.
  • Step 5: If one wave is going up and another is going down, you subtract their heights at that point.
