Could you please help me with this problem?(adsbygoogle = window.adsbygoogle || []).push({});

Light coming from an underwater source emerges from the surface in a circle. If the water is 1.0 m deep and its index of refraction is 1.333, how big is this circle of light?

Is this related to refraction of light? If so, how could I possibly know the radius of that circle?
