WebWhen a light ray enters from an optically rarer medium (which has a low refractive index) to an optically denser medium (which has a high refractive index), its speed slows down and bends towards the normal. As water is optically denser than air, a ray of light entering from air into water will bend towards the normal. 2. WebThe ability to refract light is represented by the optical density of a medium. A medium having larger refractive index is called optically denser medium. The other medium having lower refractive index is called optically rarer medium.
