  • The diagram shows three labeled components: a 'source' on the left, a vertical 'barrier' in the center, and a 'receiver' on the right.
  • Vertical measurements indicate the height of the source from the ground is labeled as 'hs' and the height of the receiver from the ground is labeled as 'hr'.
  • Horizontal distances are marked: the horizontal distance from the source to the barrier is labeled 's', and the horizontal distance from the barrier to the receiver is labeled 'v'.
  • The diagram depicts dashed lines connecting the source to the receiver, passing over the barrier, illustrating a path that forms a right-angled triangle with vertical sides labeled 'H' and 'W', and a hypotenuse connecting the source and receiver.
  • A second, fainter dashed line shows the direct connection between the source and receiver, suggesting a straight-line path.
  • Various points and segments are labeled with variables such as 'T', 'U', 'R', and 'S' to denote positions and related measurements.
