Refraction is very sensitive to any irregularities in the flatness of the surface (such as ripples or waves), which will cause local distortions or complete disintegration of the image. Turbidity in the water will veil the image behind a cloud of scattered light.
Refraction's accuracy is highly sensitive to any surface irregularities, like ripples or waves, which can cause localized distortions or total image degradation. Moreover, the clarity of the water can veil the image behind a cloud of dispersed light.
