This is due to refraction of light rays at water surfaces and air interface, which makes the apple closer to the Ryan than the original position.

Explanation:

The bending of waves of light as it passes from one medium to another due to changes in its speed is called Refraction.

The refractive index of light waves is 1 in air, while in water is 1.33.

Therefore as light rays passes through from the water to the air it bends due to the changes in its speed in the refractive medium (water) to (air) from differences in refractive index, at the water-air interface. Thus the apple appears raised to Ryan (apparent dept) which affects his target.
