Explanation:
1. This phenomenon is known as a Mirage. Its occurs when a relatively hot surface causes air around it to expand and density to decrease. This creates layers of air with different densities and causes refraction. It appears as if there is water on the road but actually we are seeing the sky.
2. When light enters a denser medium, it deflects towards normal. So in this case light beam will bend towards normal.
3. When a ray of light strikes at the surface at 90°, it causes no delfection i.e. the ray will remain intact.
4. Light will travel faster in water because speed of light is inversely proportional to density.
