Solution 6CQ
Step 1 of 3
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.
