The speed of light in a single substance doesn't tell you anything about refraction.
The angle of refraction at the boundary between two substances depends on the
speed of light in both of them ... and also, let us not forget, on the angle of incidence
at the boundary.
Refraction is the bending of waves as they enter a different medium.
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
this occurs when an object takes in light waves
Reflection: light bounces off of a surface, like a mirror.Refraction: light goes through a substance and bends. For example, white light through a prism comes out in a rainbow because the light is refracted or bent and each color has a different index of refraction.
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .

There will be refraction when light passes from one substance to the other (for example, from air to water), when the two substances have different indices of refraction, and when light passes the surface at an angle. In other cases, there is no refraction.
refraction of light
Refelction - bounces of a surface Refraction - changes speed depending on the substance it travels through Interfence - can interact with other light waves
In reflection the light bounces bach; in refraction the light passes through, but is bent at the interface.
It happens by the refraction of light.
