What is a wave barrier?


Open in App
Solution

  1. When the source moves at a speed equal to the speed of the wave, a barrier wave is produced in front of the source as each successive wave front piles on top of the previous one.
  2. This regions of constructive interference pattern is a physical reality that must be overcome if the source is to move any faster.
    2.1 A barrier wave is formed in front of the source as each successive wave front piles on top of the other.
  3. When a sound wave meets a barrier, some sound is reflected back from the front surface.
  4. In physics, a reflection is when a wave encounters a new medium that acts as a barrier.
