Answer:

'The bottom of a pond appears raised.' due to refraction phenomenon.

Explanation:

  • Whenever light travel through different medium it bends its path. so when the light travels into pond i.e air(rarer) to water (denser) it bends its path creating an illusion.
  • The bending of this light ( away the normal) and again towards the normal after reflecting from bottom of pond creates an vision as if the bottom of pond is raised a little.
  • This phenomenon is called as the refraction phenomenon.
