Answer 1

Recently , in one year , eight people in NSW, suffered severe spinal injuries caused by diving into shallow water and landing on heads. In some cases the water was clear and the bottom of the pool was plainly visible. This is happening because of refraction of light , due to refraction people are not able to judge the accurate depth of the water.
