Refraction is the bending of light as it passes through a medium with a different refractive index, such as from air to water, while reflection is the bouncing of light off a surface, such as a mirror or a pool of water. In refraction, the angle of the light wave changes as it passes from one medium to another, while in reflection, the angle of incidence (the angle between the incoming light and the normal to the surface) is equal to the angle of reflection (the angle between the reflected light and the normal to the surface).\n
What is the difference between refraction and reflection?
