Reflection
When light hits an object, the light reflects. In order for Reflection to take place, the surface must be shiny and smooth.
In a situation where the surface is smooth and shiny, the Angle of Incidence and Angle of Reflection appear. The Angle of Incidence is when light hits a surface. The Angle of Reflection reflects the surface. The Angle of both are Equal. The Normal is always at 90 degrees. For Example:

Refraction
When light hits an object, the light bends. In order for Refraction to take place, the surface must be smooth and transparent.
From the picture above, if you look closely, you can see the fingers in the water are bent unlike the fingers ouside of the water. This is because water has a higher density than air. Watch this experiment closely:

Penetration
When light hits an object, the light passes through or penetrates. In order for Penetration to take place, the surface must be clear and transparent.
When a surface is rough, the light will be distorted
