Refraction
Explanation:
When light propagates from one medium into another, its speed changes, which causes the light to reflect and refract at the boundary
The index of refraction of water is 1.33 and as light travels from water to air, it will bend away from the line perpendicular to the surface
When the incident angle is greater than 48 degrees, all the light is reflected back into the water (total internal reflection)
This refraction of light is responsible for the illusion that is why shape of the thing we see under the water surface is different from what it really is
