Questions

In the picture, а sоund wаve mоves frоm the top of the pаge towards the bottom and passes through a small hole in a barrier (point 2 on the diagram). The light areas represent regions of low pressure, and the dark areas represent high pressure. The following questions ask you to use your understanding of wave behavior to explain what is happening at certain points.    Image Description The image shows horizontal evenly spaced bands of dark and light that extend from the top to a barrier with a hole at the bottom. The distance between two adjacent white bands is labeled 1, the hole is labeled 2. In the next three questions, use your understanding of wave behavior to explain what is happening at certain points.
