Explanation / Answer
This optical effect is due to refraction. As lightpasses from one transparent medium to another, it changes speed,and bends.It depends on the refractive index ofthe mediums and the angle between the light ray and the lineperpendicular (normal) to the surface separatingthe two mediums.
