Explain why an object in water always appears to be at a depth shallower than it actually is? Why do people sometimes sustain neck and spinal injuries when diving into unfamiliar ponds or waters?
Step 1 of 3</p>
Let us assume that the depth of swimming pool is f. A light ray BB travels upward from one of the corner of swimming pool and is incident at angle θ1 with vertical on the water surface of the swimming pool.
This ray gets refracted in air at water air interface at an angle θ2 as shown in figure below. This ray will bend away from normal as shown in figure. This ray will reach to the observer.
Step 2 of 3</p>
If we traced back this ray then this ray seems to come from point B’. For the observer, point B’ is depth of the pool which is above from the point B (actual depth of pool). Thus, to observer depth of swimming pool appears to be f1 instead of f or we can say swimming pool appears shallower than it actually is.
